If the run fails, it should report that and return a non-zero exit
status. The simplest way to do that is with `run(..., check=True)`,
which raises a `CalledProcessError`.
Move the dist-aarch64-linux CI job to an aarch64 runner instead of
cross-compiling it from an x86 one. This will make it possible to
perform optimisations such as LTO, PGO and BOLT later on.
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.

Promote powerpc64le-unknown-linux-musl to tier 2 with host tools
MCP: https://github.com/rust-lang/compiler-team/issues/803
I'm using crosstool-ng for building a toolchain because GCC 9 from `musl-toolchain.sh` has float ABI issues (?) and can't compile LLVM, and writing a crosstool-ng config for a target feels less hacky than yet another target specific shell script. I also defined a kernel version, since there wasn't one specified before. If a lower version is desired, just let me know. I also tried to match the rust configure args with the loongarch64 musl tier 2 target.
The resulting compiler works fine, built with `DEPLOY=1 ./src/ci/docker/run.sh dist-powerpc64le-linux` and tested on Alpine Linux in a VM and on a bare metal POWER8 machine:

CI: move `dist-arm-linux` to an ARM runner
First, I want to test whether we could actually move this to a free runner, vs moving to the 8-core ARM runner.

Replace black with ruff in `tidy`
`ruff` can both lint and format Python code (in fact, it should be a mostly drop-in replacement for `black` in terms of formatting), so it's not needed to use `black` anymore. This PR removes `black` and replaces it with `ruff`, to get rid of one Python dependency, and also to make Python formatting faster (although that's a small thing).
If we decide to merge this, we'll need to "reformat the world" - `ruff` is not perfectly compatible with `black`, and it also looks like `black` was actually ignoring some files before. I tried it locally (`./x test tidy --extra-checks=py:fmt --bless`) and it also reformatted some code in subtrees (e.g. `clippy` or `rustc_codegen_gcc`) - I'm not sure how to handle that.
use `--exact` on `--skip` to avoid unintended substring matches
Without the `--exact` flag, using `--skip tests/rustdoc` can unintentionally skip other tests that match as substrings such as `rustdoc-gui`, `rustdoc-js`, etc.
For debugging, run: `./x.py --stage 2 test rustdoc-ui --skip tests/rustdoc` and `./x.py --stage 2 test rustdoc-ui --skip tests/rustdoc -- --exact`
