This makes tidy warn on the presence of any directives it does not recognize.
There are changes in compiletest because that file used "tidy-alphabet" instead of "tidy-alphabetical".
centralize build stamp logic
This PR brings all the stamp file handling into one place inside `build_stamp` module, which takes care of everything related to build stamps. By doing this, we cut down on duplicated code and types and keep the codebase easier to maintain and more consistent.
Main goals are:
- Make stamp handling stricter so we don't have to pass `Path`s around and manually `join` on arbitrary directories
- Keep all stamp-related logic in one place
- Make it easier to test and debug
- Avoid duplication
- Keep things simple and well-documented

ci: Move dist-aarch64-linux to an aarch64 runner
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.

compiletest: include stage0-sysroot libstd dylib in recipe dylib search path
To fix some of the failures in `COMPILETEST_FORCE_STAGE0=1 ./x test run-make --stage 0`. Specifically,
```
COMPILETEST_FORCE_STAGE0=1 ./x test tests/run-make/rustdoc-default-output/ --stage 0
```
should now pass.
Fixes#135373. (As in, make *some* of the `run-make` tests pass, other `run-make` tests fail for various reasons against stage0, and generally `run-make` tests are not guaranteed to pass at stage 0.)
