It's not used in `rustc_middle`, and `rustc_resolve` is a better place
for it.

It's not used in `rustc_middle`, and `rustc_trait_selection` is a better
place for it.

Next to all the other `EarlyParamRegion` pieces.

It's only used in `rustc_hir_typeck`.

It's only used in `rustc_infer`.

The fields are public, so this doesn't need a method, normal
deconstruction and/or field access is good enough.

It's identical to `TyCtxt::get_all_attrs` except it takes `DefId`
instead of `impl Into<DefIf>`.

It's only used in `rustc_hir_typeck`.

- Put them in the module that defines the type.
- Add some `WithCachedTypeInfo<T>` asserts for consistency.

fix: Only "close the window" when its the last annotated file

While comparing the Unicode theme output of `rustc` and `annotate-snippets`, I found that `rustc` would ["close the window"](https://github.com/rust-lang/rust/blob/686bc1c5f9c06762b18082434c04d514acf6707e/compiler/rustc_errors/src/emitter.rs#L1025-L1027) (draw a `╰╴`), even though there were other annotated files that followed the current one. This PR makes it so the emitter will only "close the window" on the last annotated file.

Before:
```
error[E0624]: method `method` is private
   ╭▸ $DIR/close_window.rs:9:7
   │
LL │     s.method();
   ╰╴      ━━━━━━ private method
   │
   ⸬ $DIR/auxiliary/close_window.rs:3:5
   │
LL │     fn method(&self) {}
   ╰╴    ──────────────── private method defined here
```

After:
```
error[E0624]: method `method` is private
   ╭▸ $DIR/close_window.rs:9:7
   │
LL │     s.method();
   │       ━━━━━━ private method
   │
   ⸬ $DIR/auxiliary/close_window.rs:3:5
   │
LL │     fn method(&self) {}
   ╰╴    ──────────────── private method defined here
