[bootstrap] Distribute split debuginfo if present
If debuginfo has been requested in `config.toml`, it should be packaged alongside the appropriate binary when running `x.py dist`.
Currently, this is only implemented for msvc environments where split debuginfo is (basically) the only option. I've tested that this correctly packages the `.pdb` for each binary in the various dist packages.
jsondocck: Replace `jsonpath_lib` with `jsonpath-rust`
The current jsonpath implementation we use isn't spec-compliant, and is buggy. See https://github.com/freestrings/jsonpath/issues/91
To solve it, it's replaced with https://github.com/besok/jsonpath-rust. This is spec-compiant, and doesn't have a really awkward bug we need to always dance around.
Unfortunately, this requires rewriting almost every test, as the behaviour of `[?(```@`,``` which is *extremely* common was changed. (But the new behaviour makes way more sense, and isn't buggy with tripply nested selectors)
Unblocks #110406. Makes #100515 much easier as we don't need to explain the broken JSONPath implementation
Best reviewed commit-by-commit. The first does the replacement. The next two rewrite the test-suite mechanically. The last rewrites the test-suite by hand.

[bootstrap] Use llvm_runtimes for compiler-rt
Trying to enable `compiler-rt` via `LLVM_ENABLE_PROJECTS` is no longer a supported option in LLVM, and gives you nasty warnings:
```
Using LLVM_ENABLE_PROJECTS=compiler-rt is deprecated now, and will become a
fatal error in the LLVM 21 release. Please use
-DLLVM_ENABLE_RUNTIMES=compiler-rt or see the instructions at
https://compiler-rt.llvm.org/ for building the runtimes.
```

bootstrap: add `--ci` flag
To make bootstrap act like it's running on CI, we had to override the `GITHUB_ACTIONS` environment variable which is a hidden detail of `CiEnv::is_ci`. Now, we can use the `--ci` flag directly on bootstrap which will be documented automatically from `x --help`. This also helps us to avoid race conditions on bootstrap (overriding `GITHUB_ACTIONS` env in each test can cause that if we run the tests in parallel) tests.
It's very useful. There are some false positives involving integration
tests in `rustc_pattern_analysis` and `rustc_serialize`. There is also a
false positive involving `rustc_driver_impl`'s
`rustc_randomized_layouts` feature. And I removed a `rustc_span` mention
in a doc comment in `rustc_log` because it wasn't integral to the
comment but caused a dev-dependency.
Leave a breadcrumb towards bootstrap config documentation in `bootstrap.toml`
I was curious as to the possible bootstrap options I can put in config.toml, but had some trouble figuring it out. There is no obvious documentation in `config.toml` (obviously), the documentation in src/bootstrap/defaults is *nice*, but also rather sparse, by design.
I had to dive into the parsing code, and stuble upon [a very helpful doc comment](https://github.com/rust-lang/rust/blob/30f168ef811aec63124eac677e14699baa9395bd/src/bootstrap/src/core/config/config.rs#L181) there to realize that `config.example.toml` *exists*, and that it does, indeed, answer all of my questions.
So I figured it might be worth making this journey a bit easier for future contributors and add mention the `config.example.toml` directly in `config.toml`.
Now, since #137081 is in-flight which would rename `config(.example)?.toml` to `bootstrap(.example)?.toml`, I figure it's better to wait until that one lands, and submit the "new", "correct" filename upfront, instead of landing `config.toml` now and updating it to `boostrap.toml` later.
`@rustbot` blocked #137081
If debuginfo has been requested in `config.toml`, it should be packaged

change config.toml to bootstrap.toml
Currently, both Bootstrap and Cargo uses same name as their configuration file, which can be confusing. This PR is based on a discussion to rename `config.toml` to `bootstrap.toml` for Bootstrap. Closes: https://github.com/rust-lang/rust/issues/126875.
I have split the PR into atomic commits to make it easier to review. Once the changes are finalized, I will squash them. I am particularly concerned about the changes made to modules that are not part of Bootstrap. How should we handle those changes? Should we ping the respective maintainers?
Install licenses into `share/doc/rust/licenses`
This changes the path from "licences" to "licenses" for consistency
across the repo, including the usage directly around this line. This is
a US/UK spelling difference, but I believe the US spelling is also more
common in open source in general.
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.

use `expect` instead of `allow`
This is more useful than `allow` as compiler will force us to remove rules that are no longer valid (we already got a few of them in this change).
