Add gha problem matcher
These regexes capture rustfmt errors, panics and regular Rust errors in CI and automatically add messages in the diff view. This should make it simpler to quickly see what went wrong without having to scroll through CI logs.
We can fine tune the regexes or add more matchers after having a look at how it actually works in practice
The relevant documentation can be found at https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md

Replace fvdl with ffx, allow test without install
Along with replacing fvdl uses with the equivalent ffx commands, this also switches from using the install path for libstd-*.so and libtest-*.so to using the build directory (now passed on the command line). The user no longer needs to run x.py install before running tests now, and the correct libstd and libtest are detected on run instead of startup so the test runner can handle recompilations after starting the testing environment.

Add support for test tmpdir to fuchsia test runner
Also format the script to keep the code nice.
This fixes the `tests/ui/std/switch-stdout.rs` test on Fuchsia.

CI: merge `msvc` test CI jobs
Merges `msvc` jobs together to save CI time. Currently, both runners take about 1h 15 minutes, but nowadays it should be possible to just run everything in a single job.
CI run: https://github.com/rust-lang/rust/actions/runs/5272144087/jobs/9534015536?pr=112633 (both finish under ~1h 35 minutes)
After this change, we no longer test both `x.py` and `x.ps1`, but I don't suppose that it's worth it to spend 1.5 hours of additional CI time just for that. I suggest to run all tests using e.g. `x.py` and then run just `x.ps1 test --stage 2 --force-rerun tests/<single-quick-test>`.
Also I'm not sure if it's worth it to keep using the Makefile for this.
Run tests on PGO/LTO/BOLT optimized dist artifacts
This PR adds baisc tests for the optimized dist builds on x64 Linux and Windows. A subset of the test suite is run, so it's not perfect, but it's better than the status quo (which is basically no testing at all, apart from the perf bot on Linux).

Print the full arguments passed to `./configure` in CI
This is useful to replicate CI failures locally. Before, the arguments would be truncated and it would be hard to tell what it was actually doing.
Before:
```
configure: build.configure-args := ['--build=x86_64-unknown-linux-gnu', '--save-t ...
```
After:
```
configure: build.configure-args := ['--build=x86_64-unknown-linux-gnu', '--save-toolstates=/tmp/toolstate/toolstates.json', '--enable-verbose', '--enable-sccache', '--disable-manage-submodules', '--enable-locked-deps', '--enable-cargo-native-static', '--set', 'rust.codegen-units-std=1', '--set', 'dist.compression-profile=balanced', '--dist-compression-formats=xz', '--disable-dist-src', '--set', 'rust.download-rustc=if-unchanged', '--release-channel=nightly', '--enable-debug-assertions', '--enable-overflow-checks', '--enable-llvm-assertions', '--set', 'rust.verify-llvm-ir', '--set', 'llvm.download-ci-llvm=if-available', '--enable-missing-tools']

Do not build docs in try builds
This PR adds a new environment variable to the optimized build Python script, which causes it to ignore certain parts of the final `dist` build (mainly docs) in try builds. This reduces the duration of try builds by ~10 minutes.
Replace const eval limit by a lint and add an exponential backoff warning
The lint triggers at the first power of 2 that comes after 1 million function calls or traversed back-edges (takes less than a second on usual programs). After the first emission, an unsilenceable warning is repeated at every following power of 2 terminators, causing it to get reported less and less the longer the evaluation runs.

Remove aws cli install.
All runner images have the AWS CLI 2 installed, so there isn't a really strong reason to install our own version anymore.
The version we were installing was 1.27.122. The runner images currently have 2.11.x (the exact version varies by image).
I do not have the means to really test if the new version has any issues. I looked at all the `aws` commands, and none of them seem to be doing anything unusual. The page at https://docs.aws.amazon.com/cli/latest/userguide/cliv2-migration-changes.html contains a list of all the breaking changes, and I didn't see anything that looked important.
