Update LLVM to 21.1.3
Fixes https://github.com/rust-lang/rust/issues/146742.
After rust-lang/rust#146124, we need more space to run x86_64-gnu-distcheck if building LLVM from source. According to the building log, the space freed by `free-disk-space-linux.sh` is not entirely available.
```
You are running out of disk space.
The runner will stop working when the machine runs out of disk space.
Free space left: 98 MB

Most new API has an associated ACP that is useful to reference, but it
doesn't appear anywhere on the template for new tracking issues. Update
this template to include a link to the ACP.
rustdoc has its own issue template now, mention that.
swap the order of the last two sentances so it reads more like
a typical if/else chain (base case listed last).

Free disk space on Windows 2025 runners
I've managed to reduce the time deletion takes by:
- Using powershell, which is generally faster for filesystem operations than msys2
- Performing deletions concurrently then waiting for them all to complete
It still takes 2-10 mins but that's not too bad.
Unfortunately, the separate spellcheck GHA workflow does not really work
with homu, if we would like to enforce the invariant that PR CI is a
subset of Full CI (modulo carve outs).
This is not prejudice against a reland of a `typos`-based spellcheck, it
just probably has to go through the "usual" CI flow with bootstrap, so
that it can work with homu.
Add an aarch64-msvc build running on ARM64 Windows
Resurrecting rust-lang/rust#126341
Per <https://github.com/rust-lang/rfcs/pull/3817> we intend to promote `aarch64-pc-windows-msvc` to Tier 1. As part of that work, we are adding a pre-merge CI job to validate that changes do not break this target.
Additionally, for consistency, the `dist-aarch64-msvc` job will also be run on Arm64 Windows runners.

Assign dependency bump PRs to me
These PRs sometimes get lost as GH reduces their visibility, so I wanted to get an assignment so I can help these PRs land
setup typos check in CI
This allows to check typos in CI, currently for compiler only (to reduce commit size with fixes). With current setup, exclude list is quite short, so it worth trying?
Also includes commits with actual typo fixes.
MCP: https://github.com/rust-lang/compiler-team/issues/817
typos check currently turned for:
* ./compiler
* ./library
* ./src/bootstrap
* ./src/librustdoc
After merging, PRs which enables checks for other crates (tools) can be implemented too.
Found typos will **not break** other jobs immediately: (tests, building compiler for perf run). Job will be marked as red on completion in ~ 20 secs, so you will not forget to fix it whenever you want, before merging pr.
Check typos: `python x.py test tidy --extra-checks=spellcheck`
Apply typo fixes: `python x.py test tidy --extra-checks=spellcheck:fix` (in case if there only 1 suggestion of each typo)
Current fail in this pr is expected and shows how typo errors emitted. Commit with error will be removed after r+.
That branch is essentially the same as the `try` branch, it also needs S3 permissions.
Long term, we should move rollup unrolling from rustc-perf to bors, so that we can have only a single try branch.
