bootstrap: keep all cargo test files in dist rustc-src
Cargo tests use some files that we would otherwise exclude, especially
the `cargo init` tests that are meant to deal with pre-existing `.git`
and `.hg` repos and their ignore files. Keeping these in our dist
tarball doesn't take much space, and allows distro builds to run these
tests successfully.

It's been 5 months since we deprecated this. It should be fine to drop its support now.

The description was most accurate when it was still called rustbuild,
and I presume indeed did mostly run in CI. It has become something more
so try to describe it better for current-day usage.

enable clippy for bootstrap on CI PRs (in `mingw-check` image)
Let's keep the bootstrap codebase cleaner.

bootstrap: actually allow set debuginfo-level to "line-tables-only"
I've tried to set in config.toml `rust.debuginfo-level = "line-tables-only"`, but ended with:
``` failed to parse TOML configuration 'config.toml':
data did not match any variant of untagged enum StringOrInt for key `rust.debuginfo-level`
```
Also this PR allows to set `line-directives-only` for debuginfo in config.toml too.
1. Fixes this. Alternative is remove that Deserialize and use default one:
https://github.com/rust-lang/rust/blob/0e682e9875458ebf811206a48b688e07d762d9bb/src/bootstrap/src/core/config/config.rs#L725-L728
2. Should `line-directives-only` be added too?
3. I've tried to add test to rust/src/bootstrap/src/core/config/tests.rs:
```rust
#[test]
fn rust_debuginfo() {
assert!(matches!(
parse("rust.debuginfo-level-rustc = 1").rust_debuginfo_level_rustc,
DebuginfoLevel::Limited
));
assert!(matches!(
parse("rust.debuginfo-level-rustc = \"line-tables-only\"").rust_debuginfo_level_rustc,
DebuginfoLevel::LineTablesOnly
));
}
```
But test passes before that PR too; looks like config parse tests checks something wrong? I mean, that tests check something which isn't actual bootstrap behavior.

Update how WASI toolchains are used in CI and bootstrap
This commit updates how the WASI targets are configured with their toolchain. Long ago a `config.toml` option of `wasi-root` was added to enable building with the WASI files produced by wasi-libc. Additionally for CI testing and release building the Rust toolchain has been using a hard-coded commit of wasi-libc which is bundled with the release of the `wasm32-wasip1` target, for example.
Nowadays though the wasi-sdk project, the C/C++ toolchain for WASI, is the go-to solution for compiling/linking WASI code and contains the more-or-less official releases of wasi-libc. This commit migrates CI to using wasi-sdk releases and additionally updates `bootstrap` to recognize when this is configured. This means that with `$WASI_SDK_PATH` configured there's no further configuration necessary to get a working build. Notably this also works better for the new targets of WASI as well, such as `wasm32-wasip2` and `wasm32-wasip1-threads` where the wasi-sdk release now has libraries for all targets bundled within it.

refactor clippy in bootstrap
Previously, using clippy in bootstrap was not very useful as explained in #122825. In short, regardless of the given path clippy would always check the entire compiler and std tree. This makes it impossible to run clippy on different paths with different set of rules. This PR fixes that by allowing developers to run clippy with specific rules on specific paths (e.g., we can run `x clippy compiler -Aclippy::all -Dclippy::correctness` and `x clippy library/std -Dclippy::all` and none of them will affect each other).
Resolves #122825

Previously, we were checking the LLVM stamp before fetching the submodule which leads to not being able to compile llvm on submodule updates.

libtest: also measure time in Miri
A long time ago we disabled timekeeping of the default test harness in Miri, as otherwise it would fail to run without `-Zmiri-disable-isolation`. However, since then Miri gained a "fake clock" that lets it present some deterministic notion of time when isolation is enabled.
So we could now let libtest do timekeeping again when running in Miri. That's nice as it can help detect tests that run too long. However it can also be confusing as the results with isolation can be quite different than the real time.
``@rust-lang/miri`` what do you think?

compiletest ice tracking
see https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/where.20to.20mass-add.20known.20ices.20.2F.20merging.20glacier.20into.20rust/near/429082963
This will allow us to sunset most of https://github.com/rust-lang/glacier
The rustc ices will be tracked directly inside the rust testsuite
There are a couple of .sh tests remaining that I have not ported over yet.
This adds `tests/crashes`, a file inside this directory MUST ice, otherwise it is considered test-fail.
This will be used to track ICEs from glacier and the bugtracker.
When someones pr accidentally fixes one of these ICEs, they can move the test from `crashes` into `ui` for example.
I also added a new tidy lint that warns when a test inside `tests/crashes` does not have a `//@ known-bug: ` line
the env var `COMPILETEST_VERBOSE_CRASHES` can be set to get exit code, stderr and stdout of a crash-test to aid debugging/adding tests.

skip Codegen{GCC,Cranelift} when using CI rustc
CI rustc uses the default codegen backend, therefore we can't run `CodegenGCC` and `CodegenCranelift` tests when using it.
cc `@bjorn3` (to make sure I am not doing anything wrong)

bootstrap: move all of rustc's flags to `rustc_cargo`
This ensures that `RUSTFLAGS` will be consistent between all modes of
building the compiler, so they won't trigger a rebuild by cargo. This
kind of fix was started in #119414 just for LTO flags, but it's
applicable to all kinds of flags that might be configured.
