Inspired by some of the communication issues around the stabilization of
`let`-chains, give more fine-grained information about the status of
updating style for any new syntax.
This does not change the process or blockers in any way; it only
*documents* the current state in the tracking issue. For instance, in
the case of `let`-chains, we would have checked the boxes for "Style
team decision" and "(non-blocking) Formatting has been implemented", and
not checked the box for the style guide. That would have then provided
better supporting information for any decisions.
Update library tracking issue template to set S-tracking-unimplemented
This will help people notice the `S-tracking-*` labels, and if the
tracking issue *is* implemented, they can change the label.
Discussed in a `@rust-lang/libs-api` meeting.

Store test diffs in job summaries and improve analysis formatting
This PR stores the test diffs that we already have in the post-merge workflow also into individual job summaries. This makes it easier to compare test (and later also other) diffs per job, which will be especially useful for try jobs, so that we can actually see the test diffs *before* we merge a given PR.
As a drive-by, I also made a bunch of cleanups in `citool` and in the formatting of the summary and post-merge analyses. These changes are split into self-contained commits.
The analysis can be tested locally with the following command:
```bash
$ curl https://ci-artifacts.rust-lang.org/rustc-builds/<current-sha>/metrics-<job-name>.json > metrics.json
$ cargo run --manifest-path src/ci/citool/Cargo.toml postprocess-metrics metrics.json --job-name <job-name> --parent <parent-sha> > out.md
```
For example, for [this PR](https://github.com/rust-lang/rust/pull/138523):
```bash
$ curl https://ci-artifacts.rust-lang.org/rustc-builds/282865097d138c7f0f7a7566db5b761312dd145c/metrics-aarch64-gnu.json > metrics.json
$ cargo run --manifest-path src/ci/citool/Cargo.toml postprocess-metrics metrics.json --job-name aarch64-gnu --parent d9e5539a39 > out.md
```

Improve post-merge workflow
Contains various fixes for the post-merge workflow implemented in https://github.com/rust-lang/rust/pull/138013, which were suggested on Zulip. This PR changes the grouping of test diffs and ignores doctests, as they are too noisy.
I'll post an example output (before/after this PR) in comments below.

Revert "Remove Win SDK 10.0.26100.0 from CI"
Part of #137733.
Resolves#137733.
The remove-latest-windows-sdk workaround workaround should no longer be necessary, now that we bumped (1) cargo `cc` and (2) `rustc_{codegen_ssa,llvm}` `cc`.
This reverts commit 25617c7e69, the remove-latest-windows-sdk workaround from #137753.

Rewrite the `ci.py` script in Rust
It would seem that I would learn by now that any script written in Python will become unmaintainable sooner or later, but alas..

Bump sccache in CI to 0.9.1
We haven't updated the used sccache version for years, it has accrued a bunch of fixes and features in the meantime. It now supports the `--show-adv-stats` flag, which gives a more detailed summary of the results of caching. And it can also cache Rust code, which could be useful in the future (https://github.com/rust-lang/rust/pull/136942 - although now there are no large wins).
It also supports caching PGO now, but since the PGO profiles are always different, it won't make any real difference.
https://github.com/rust-lang/rust/pull/133076 previously tried to update the version to 0.3 (CC `@klensy)`

There is a difference between the `image` (the Dockerfile), the `name` of the job (which determines also its properties) and the `full_name`, which includes the `auto/try/pr` prefix.
Make it easier to run CI jobs locally
This PR extends the Python CI script to perform a poor man's CI-like execution of a given CI job locally. It's not perfect, but it's better than nothing.
