miri core/alloc tests: do not test a 2nd target
check-aux seems to be one of the slowest runners since we started running standard library tests in Miri on it. So maybe it'd be better to reduce test coverage a bit by not doing cross-target testing of core and alloc? I don't recall finding target-specific issues in these libraries ever (and we still have the extra test coverage via our [out-of-tree nightly tests](https://github.com/rust-lang/miri-test-libstd)). This gives us more buffer to deal with the fact that the number of tests we run will only grow over time.

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.

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

This commit updates how the WASI targets are configured with their
toolchain. Long ago a `config.toml` option of `wasi-root` was added to

wasi-sdk release now has libraries for all targets bundled within it.

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.

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.

do not allow using local llvm while using rustc from ci
From: https://github.com/rust-lang/rust/issues/123586#issuecomment-2043296578
> Even if `llvm.download-ci-llvm` is set to true, `stage > 0` rustc will always use the prebuilt LLVM library which comes with ci-rustc. So I tried to use locally-built LLVM libraries in the ci-rustc by replacing the existing LLVM libraries with the locally built ones, and it appears that this is indeed a limitation of using `rust.download-rustc=true` as it fails with the following error:
>
> ```
> $ ./build/host/ci-rustc/bin/rustc --version
> ./build/host/ci-rustc/bin/rustc: symbol lookup error: /home/nimda/devspace/.other/rustc-builds/build/x86_64-unknown-linux-gnu/ci-rustc/bin/../lib/librustc_driver-a03ea465d8e03db1.so: undefined symbol: LLVMInitializeARMTargetInfo, version LLVM_18.1
> ```
>
> So, if `rust.download-rustc` is set to true and `llvm.download-ci-llvm` is false, I believe bootstrap should terminate the process (as it always uses prebuilt LLVM libraries from ci-rustc, there is no point to build LLVM locally) while parsing the configuration.

bootstrap: split cargo-miri test into separate Step
This makes it easier to test just the driver or the cargo-miri integration.
