Create a similar rollup

Covers all Arm Linux systems, and means that we can reduce the amount
of information required in the target specific pages to just the Tier
level, the maintainer, and any specific details for that target.
The clippy lint catches some things that rustc's equivalent builtin lint
does not, for example rust-lang#146940:

    error: function cannot return without recursing
        --> library/std/src/path.rs:3428:5

         | |_____^

Resolve: (Ref)Cell wrappers to deny mutation during spec resolution.

Introduces wrappers around `Cell` and `RefCell` that only allow mutation when we are not in speculative resolution. This is preparatory work for rust-lang#145108.

It would allow us to make `ImportData` and `ModuleData` sync and send safe.

Add general arm-linux.md platform doc.

Adds a new page that covers all 32-bit Arm Linux systems. This means that we can reduce the amount of information required in the target specific pages to just the Tier level, the maintainer, and any specific details for that target.

I have no changed those pages yet, though. Let's start with this.

const_caller_location to use real Span instead of `DUMMY_SP`

Clarifying usage of DUMMY_SP
Add `clippy::unconditional_recursion` to `./x clippy ci`

Rename verbosity functions in bootstrap

Just a small cleanup, these function names have been bothering me for a while. I realized that we can delete some of them outright, rather than just renaming them.

rustdoc: put the toolbar on the all item index
std: fix warning in VEXos stdio module

Fixes building `std` on the `armv7a-vex-v5` target due to an unnecessarily mutable argument in `Stdin`.

This was a stupid oversight on my part towards the end of rust-lang#145973's review process. Missed a warning and had a bad bootstrap config that didn't tell me about it when testing changes.

Job duration changes

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
