Update mdbook
This updates mdbook from 0.4.21 to 0.4.25. The list of changes is [here](https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-0425). The only user-visible changes are some changes around the theme picker, and change to the copy-to-clipboard ignoring hidden lines.
Internally there were some dependency updates and small fixes.
This also updates `clap` from 4.0.15 to 4.0.32 whose changelog is [here](https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#4032---2022-12-22). This impacts tools like cargo. I don't see anything particularly noteworthy there, though there are some small user-visible changes.
Unfortunately this required adding a hack for building `rustix` with a bootstrap tool. The comment explains why. I am unable to think of some other workaround (or even a cleaner way to set the rustflag). Ideas are welcome if you can think of alternatives. I'm struggling to even think of a long-term solution, other than asking projects not to do auto-nightly feature detection.
One medium-term solution is to avoid the clap dependency for the mdbook library (which is how rustix gets pulled in). That is one of my goals for the 0.5 release of mdbook, but that probably won't happen until later this year. It would also require dropping clap from `rustbook` and using some other means to parse arguments (there's only two options, so it can probably be done manually).
rustdoc: remove unnecessary DOM class `h1.fqn`
It's misleading. The main heading sometimes isn't an fully qualified name at all.
It's also redundant. It's always a child of `div.main-heading`, so just use that.
Remove duplicate sha-1 dependency
[`sha-1`](https://crates.io/crates/sha-1) is more or less a duplicate of [`sha1`](https://crates.io/crates/sha1). The `sha-1` is deprecated and no longer updated. This updates the dependencies to use the new name.
Some other dependencies that got updated as a consequence:
* The updated pest dependencies are currently only used by mdbook, and shouldn't have any issues.
* ucd-trie 0.1.3 to 0.1.5: No changelog, but looks like some tables were updated for new unicode versions: https://github.com/BurntSushi/ucd-generate/commits/master/ucd-trie. This is only used by pest (and thus mdbook).
* thiserror 1.33 to 1.38: Nothing significant in the notes at https://github.com/dtolnay/thiserror/releases.
rustdoc: rename CSS rustdoc-toggle -> toggle and toggle -> settings-toggle
This swaps things around so that the class that gets used more often has the shorter name.
It's misleading. The main heading sometimes isn't an fully qualified name at all.
It's also redundant. It's always a child of `div.main-heading`, so just use that.
Render missing generics suggestion verbosely
It's a bit easier to read like this, especially ones that are appending new generics onto an existing list, like ": `, T`" which render somewhat poorly inline.
Also don't suggest `dyn` as a type parameter to add, even if technically that's valid in edition 2015.

Fix reexport of `doc(hidden)` item
Part of #59368.
It doesn't fix the `doc(inline)` nor the `doc(hidden)` on macro. I'll do it in a follow-up PR.
r? `@notriddle`
This is useful for rust-lang/rust to allow setting a sysroot that's
*only* for build scripts, different from the regular sysroot passed in
RUSTFLAGS (since cargo doesn't apply RUSTFLAGS to build scripts or
proc-macros).
That said, the exact motivation is not particularly important: this
fixes a regression from
https://github.com/rust-lang/rust-clippy/pull/9881/commits/5907e9155ed7f1312d108aa2110853472da3b029#r1060215684.
Note that only RUSTFLAGS is tested in the new integration test; passing
--sysroot through `clippy-driver` never worked as far as I can tell, and
no one is using it, so I didn't fix it here.
remove unreachable error code `E0490`
AFAIK, the untested and undocumented error code `E0490` is now unreachable, it was from the days of the original borrow checker.

Harden the pre-tyctxt query system against accidental recomputation
While the current compiler has no issues where we `take` and then compute the query again, in https://github.com/rust-lang/rust/pull/105462 I accidentally introduced such a case.
I also took the opportunity to remove `peek_mut`, which is only ever used for `global_tcx` to then invoke `enter`. I added an `enter` method directly on the query.

Stabilize `::{core,std}::pin::pin!`
As discussed [over here](https://github.com/rust-lang/rust/issues/93178#issuecomment-1295843548), it looks like a decent time to stabilize the `pin!` macro.
### Public API
```rust
// in module `core::pin`
/// API: `fn pin<T>($value: T) -> Pin<&'local mut T>`
pub macro pin($value:expr $(,)?) {
…
}
```
- Tracking issue: #93178
(now all this needs is an FCP by the proper team?)
Revert "warn newer available version of the x tool"
Reverts rust-lang/rust#104552
Running the x executable directly created an [issue](https://github.com/rust-lang/rust/issues/106469) here. There are other options for warning a user that a newer version of x exists in the issue's discussion as well.

Use CI LLVM in `test-various` builder
It was disabled because it needs `lld`, but since #104748 was merged it is no longer needed.
This will speed this test, since it no longer needs to build LLVM.
