make it possible to use stage0 libtest on compiletest
With https://github.com/rust-lang/rust/pull/119899, building the library tree will require a stage 1 compiler. This is because `compiletest` is defined as a `ToolStd` (since https://github.com/rust-lang/rust/pull/68019) in order to use the in-tree library. As a result, https://github.com/rust-lang/rust/pull/119899 makes certain development workflows more difficult as changes on the compiler tree will now require recompiling `compiletest` each time.
This PR allows switching `ToolStd` to `ToolBootstrap` with a simple boolean option in `bootstrap.toml` to allow `compiletest` to use the stage 0 `libtest` instead.
The changes under `src/ci` are clearly intended to make sure that `compiletest` doesn't break during future bootstrap beta bumps.
Update sccache to 0.10.0
This time, does it also for Windows and macOS. This unifies the sccache version across all OSes that we use.

Pass `CI_JOB_DOC_URL` to Docker
Fix-up for https://github.com/rust-lang/rust/pull/136911. I always forget to pass new environment variables to Docker images.. 🤦♂️

Add `dist::Gcc` build step
This PR adds a `dist:Gcc` bootstrap step to distribute a prebuilt `libgccjit.so` from CI on x64 Linux.
With primed sccache, the build takes ~4 minutes on CI, and produces a 50 MiB archive.
I want to land this before adding something akin to `[gcc] download-ci-gcc = true`, to already have the artifacts available on CI, to make it easier to setup the download merge-base logic.

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..

Build GCC on CI
Previously, we have downloaded a specific commit of GCC and prebuilt it inside Docker using the `build-gccjit.sh` script. This PR removes that scripts and uses the bootstrap GCC step. This allows us to use the `src/gcc` submodule for determining which GCC should be built, and it also moves the logic closer to LLVM, which is also built by bootstrap.
A few things to note:
- The `sccache` option is currently in the `llvm` block, so the GCC build uses `llvm.ccache`, which is a bit weird :) We could either add `gcc.ccache`, or (what I think would be better) to just move `ccache` to the `build` section, as I don't think that it will be necessary to use ccache for LLVM, but not for GCC.
- When the GCC codegen backend is built, it needs to depend on a step that first builds GCC. This is currently done in a hacky way. The proper solution is to create a separate step for the GCC codegen backend, but that is a larger change. Let me know what you think.

Add rustdoc-gui regression test for #137082
Fixes https://github.com/rust-lang/rust/issues/137082.
Added new commands in `browser-ui-test` allowing us to add a regression test for #137082 and also another to copy code examples content.

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)`

Revert "CI: build FreeBSD artifacts on FreeBSD 13.4"
This reverts commit cf34545720.
That commit led to a regression of
https://github.com/rust-lang/rust/issues/132185 . So my analysis that the problem lay in FreeBSD 13.2's specific LLVM version was clearly wrong. Revert that commit until we can figure out the real root cause.
Fixes#132185
