This is a follow up to the following pull requests:
- flutter#124514

I was finally able to reproduce this bug and found out why it was happening. Consider this code:

```dart
GestureDetector(
  behavior: HitTestBehavior.translucent,
  // Note: Make sure onTap is not null to ensure events
  // are captured by `GestureDetector`
  onTap: () {},
  child: _shouldShowSlider
    ? Slider(value: _value, onChanged: _handleSlide)
    : const SizedBox.shrink().
)
```

Runtime exception happens when:

1. User taps and holds the Slider (drag callback captured by `GestureDetector`)
2. `_shouldShowSlider` changes to false, Slider disappears and unmounts, and unregisters `_handleSlide`. But the callback is still registered by `GestureDetector`
3. Users moves finger as if Slider were still there
4. Drag callback is invoked, `_SliderState.showValueIndicator` is called
5. Exception - Slider is already disposed

This pull request fixes it by adding a mounted check inside `_SliderState.showValueIndicator` to ensure the Slider is actually mounted at the time of invoking drag event callback. I've added a unit test that will fail without this change.

The error stack trace is:

```
The following assertion was thrown while handling a gesture:
This widget has been unmounted, so the State no longer has a context (and should be considered
defunct).
Consider canceling any active work during "dispose" or using the "mounted" getter to determine if
the State is still active.

These values are generated since flutter#135279, but I didn't know to add the new keys to this list to get them to upload. 

Failed to do so in flutter#135645, I believe the mistake there was putting them in `_kCommonScoreKeys`, which is also used in "E2E" tests, that don't get full trace data, only high level `FrameTiming` packets.

A test was failing silently because of this (see
flutter#144353 and fixed in
flutter#144709). The failure went
undetected for months. Ideally, this should have been a regular
non-silent failure. This change makes that so. `package:test` can
properly handle reported exceptions outside of test cases. With this
change, the test fails as follows:

```
00:03 +82: Smoke test material/color_scheme/dynamic_content_color.0.dart
══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞════════════════════════════════════════════════════
The following assertion was thrown running a test (but after the test had completed):
setState() called after dispose(): _DynamicColorExampleState#1cd37(lifecycle state: defunct, not
mounted)
This error happens if you call setState() on a State object for a widget that no longer appears in
the widget tree (e.g., whose parent widget no longer includes the widget in its build). This error
can occur when code calls setState() from a timer or an animation callback.
The preferred solution is to cancel the timer or stop listening to the animation in the dispose()
callback. Another solution is to check the "mounted" property of this object before calling
setState() to ensure the object is still in the tree.
This error might indicate a memory leak if setState() is being called because another object is
retaining a reference to this State object after it has been removed from the tree. To avoid memory
leaks, consider breaking the reference to this object during dispose().

When the exception was thrown, this was the stack:

Reason for reverting: This has broken the tree because some tests are still failing post completion. This particular one looks like it might have to do with a gold image not existing.

A test was failing silently because of this (see flutter#144353 and fixed in flutter#144709). The failure went undetected for months. Ideally, this should have been a regular non-silent failure. This change makes that so. `package:test` can properly handle reported exceptions outside of test cases. With this change, the test fails as follows:

```
00:03 +82: Smoke test material/color_scheme/dynamic_content_color.0.dart
══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞════════════════════════════════════════════════════
The following assertion was thrown running a test (but after the test had completed):
setState() called after dispose(): _DynamicColorExampleState#1cd37(lifecycle state: defunct, not
mounted)
This error happens if you call setState() on a State object for a widget that no longer appears in
the widget tree (e.g., whose parent widget no longer includes the widget in its build). This error
can occur when code calls setState() from a timer or an animation callback.
The preferred solution is to cancel the timer or stop listening to the animation in the dispose()
callback. Another solution is to check the "mounted" property of this object before calling
setState() to ensure the object is still in the tree.
This error might indicate a memory leak if setState() is being called because another object is
retaining a reference to this State object after it has been removed from the tree. To avoid memory
leaks, consider breaking the reference to this object during dispose().

When the exception was thrown, this was the stack:
#0      State.setState.<anonymous closure> (package:flutter/src/widgets/framework.dart:1167:9)

When attempting to release the Flutter 3.24.1 hotfix, Flutter framework post submits failed due to the following error:

```

```

I've updated the tests to include the listed artifact.  

### Open questions
1. Is it possible that the test failed only on the first binary?
2. Do we expect a need to add the remainder of the [entitlement changes](flutter/engine@c9b9d57)?
3. I am under the assumption that the bots pull from master and are not branch specific, is this a correct assumption?

### Problem

Enabling the Swift Package Manager feature caused post-submit tests to fail on Mac x64 hosts:

<details>
<summary>Example error...</summary>

https://ci.chromium.org/ui/p/flutter/builders/prod/Mac_ios%20rrect_blur_perf_ios__timeline_summary/575/overview

```
� ... flutter --verbose assemble ... -dIosArchs=x86_64 ... profile_unpack_ios

Exception: Binary ... build/ios/Profile-iphoneos/Flutter.framework/Flutter does not contain x86_64.

<asynchronous suspension>
...
```

</details>

### Reproduction

On a mac x64 host:

1. Switch to the latest master channel: `flutter channel master ; flutter upgrade`
1. Disable the Swift Package Manager feature: `flutter config --no-enable-swift-package-manager`
2. Create a Flutter project
2. [Edit the Xcode project manually to add the prepare pre-action](https://docs.flutter.dev/packages-and-plugins/swift-package-manager/for-app-developers#step-2-add-run-prepare-flutter-framework-script-pre-action)
3. Run `flutter run` (`flutter build ios` does not reproduce this issue).

### Background

Previously, the Flutter framework was unpacked in the Xcode target's build. Unfortunately, this happens after Swift packages are built; this prevented Swift packages from using the Flutter framework.

To fix this, we added an Xcode pre-action that unpacks the Flutter framework _before_ Swift Package Manager builds packages. The Xcode target still runs the Flutter framework unpack step, but this step no-ops if the unpack step has the exact same inputs. 

```mermaid
flowchart LR
  A[flutter run -d iphone] --> B(Build Xcode project)
  B --> C(Xcode 'prepare framework' pre-action)
  B --> G[Build Swift packages]
  B --> D(Build 'Runner' target)
  C --> E[Unpack Flutter framework #1]
  D --> F["
  Unpack Flutter framework #2
  (No-ops if inputs are same as #1)
  "]
```

flutter#150052 added an optimization that made it more likely the second unpack step no-ops by fixing a case where the target architecture input could be different:

> When using SwiftPM, we use `flutter assemble` in an Xcode Pre-action to run the `debug_unpack_macos` (or profile/release) target. This target is also later used in a Run Script build phase. Depending on `ARCHS` build setting, the Flutter/FlutterMacOS binary is thinned. In the Run Script build phase, `ARCHS` is filtered to the active arch. However, in the Pre-action it doesn't always filter to the active arch. As a workaround, assume arm64 if the [`NATIVE_ARCH`](https://developer.apple.com/documentation/xcode/build-settings-reference/#NATIVEARCH) is arm, otherwise assume x86_64.

This optimization is only applied if [`ONLY_ACTIVE_ARCH`](https://developer.apple.com/library/archive/documentation/DeveloperTools/Reference/XcodeBuildSettingRef/1-Build_Setting_Reference/build_setting_ref.html#//apple_ref/doc/uid/TP40003931-CH3-SW157) is `YES`.

It specifies whether the product includes only object code for the native architecture.

### Problem

`buildXcodeProject` incorrectly always sets `ONLY_ACTIVE_ARCH` to `YES` if the Xcode built is for a single architecture:

https://github.com/flutter/flutter/blob/6abef222514e8039bde5c47ab7864abbc4caf7e8/packages/flutter_tools/lib/src/ios/mac.dart#L353-L361

This is incorrect! If the host architecture is `x64` but the target architecture is `arm64`, [`ONLY_ACTIVE_ARCH`](https://developer.apple.com/library/archive/documentation/DeveloperTools/Reference/XcodeBuildSettingRef/1-Build_Setting_Reference/build_setting_ref.html#//apple_ref/doc/uid/TP40003931-CH3-SW157) should be `NO`.

This caused the prepare pre-action to incorrectly use x64 as the target architecture for arm64 devices on an x64 host, which in turn caused builds to fail if Swift Package Manager was enabled.

### Solution

This change updates `buildXcodeProject` to set `ONLY_ACTIVE_ARCH` correctly.

This change also updates the prepare pre-action's to be more conservative in applying the optimization that filters the target architecture. This ensures that the build still works (but without the optimization) if `ONLY_ACTIVE_ARCH` is incorrectly set.

This unblocks: flutter#151567

### DeviceLab test

This problem reproduces if you `flutter run` to an iPhone Arm64 device from an x64 mac host with the Swift Package Manager feature enabled.

I ran an affected DeviceLab test to verify the fix works as expected:

The crash indicates that FlutterJNI is returning a nullptr
SurfaceControl.Transaction. That likely indicates that we're trying to
rasterize a frame before the platform view controller is setup.
Potentially a startup race?

At any rate, if the PVC is null that means there is no platform views -
so it should be safe to create a tx on the fly. Interestingly I cannot
repro this locally even on the same device.

Currently when using a `CustomScrollView`, screen readers cannot list or
move focus to elements that are outside the current Viewport and cache
extent because we do not create semantic nodes for these elements.

This change introduces `SliverEnsureSemantics` which ensures its sliver
child is included in the semantics tree, whether or not it is currently
visible on the screen or within the cache extent. This way screen
readers are aware the elements are there and can navigate to them /
create accessibility traversal menus with this information.
* Under the hood a new flag has been added to `RenderSliver` called
`ensureSemantics`. `RenderViewportBase` uses this in its
`visitChildrenForSemantics` to ensure a sliver is visited when creating
the semantics tree. Previously a sliver was not visited if it was not
visible or within the cache extent. `RenderViewportBase` also uses this
in `describeSemanticsClip` and `describeApproximatePaintClip` to ensure
a sliver child that wants to "ensure semantics" is not clipped out if it
is not currently visible in the viewport or outside the cache extent.
* `RenderSliverMultiBoxAdaptor.semanticBounds` now leverages its first
child as an anchor for assistive technologies to be able to reach it if
the Sliver is a child of `SliverEnsureSemantics`. If not it will still
be dropped from the semantics tree.
* `RenderProxySliver` now considers child overrides of `semanticBounds`.

On the engine side we move from using a joystick method to scroll with
`SemanticsAction.scrollUp` and `SemanticsAction.scrollDown` to using
`SemanticsAction.scrollToOffset` completely letting the browser drive
the scrolling with its current dom scroll position "scrollTop" or
"scrollLeft". This is possible by calculating the total quantity of
content under the scrollable and sizing the scroll element based on
that.

This change reverts the following previous change:
Currently when using a `CustomScrollView`, screen readers cannot list or
move focus to elements that are outside the current Viewport and cache
extent because we do not create semantic nodes for these elements.

This change introduces `SliverEnsureSemantics` which ensures its sliver
child is included in the semantics tree, whether or not it is currently
visible on the screen or within the cache extent. This way screen
readers are aware the elements are there and can navigate to them /
create accessibility traversal menus with this information.
* Under the hood a new flag has been added to `RenderSliver` called
`ensureSemantics`. `RenderViewportBase` uses this in its
`visitChildrenForSemantics` to ensure a sliver is visited when creating
the semantics tree. Previously a sliver was not visited if it was not
visible or within the cache extent. `RenderViewportBase` also uses this
in `describeSemanticsClip` and `describeApproximatePaintClip` to ensure
a sliver child that wants to "ensure semantics" is not clipped out if it
is not currently visible in the viewport or outside the cache extent.
* `RenderSliverMultiBoxAdaptor.semanticBounds` now leverages its first
child as an anchor for assistive technologies to be able to reach it if
the Sliver is a child of `SliverEnsureSemantics`. If not it will still
be dropped from the semantics tree.
* `RenderProxySliver` now considers child overrides of `semanticBounds`.

On the engine side we move from using a joystick method to scroll with
`SemanticsAction.scrollUp` and `SemanticsAction.scrollDown` to using
`SemanticsAction.scrollToOffset` completely letting the browser drive
the scrolling with its current dom scroll position "scrollTop" or
"scrollLeft". This is possible by calculating the total quantity of
content under the scrollable and sizing the scroll element based on
that.
