CFI: Monomorphize transparent ADTs before typeid
Monomorphise `#[repr(transparent)]` parameterized ADTs before turning them into an Itanium mangled String.
`#[repr(transparent)]` ADTs currently use the single field to represent them in their CFI type ID to ensure that they are compatible. However, if that type involves a type parameter instantiated at the ADT level, as in `ManuallyDrop`, this will currently ICE as the `Parameter` type cannot be mangled. Since this happens at lowering time, it should always be concrete after substitution.
Fixes #106230

Nilstrieb:no-merge-commits-for-you-only-bors-is-allowed-to-do-that, r=jyn514
Add tidy check to deny merge commits
This will prevent users with the pre-push hook from pushing a merge commit.
Exceptions are added for subtree updates. These exceptions are a little hacky and may be non-exhaustive but can be extended in the future.
I added a link to `@jyn514's` blog post for the error case because that's the best resource to solve merge commits. But it would probably be better if it was integrated into https://rustc-dev-guide.rust-lang.org/git.html#no-merge-policy, then we could link that instead.

This makes it easier to see them (and makes people go owo).

Before:
```
Testing ["rustc_interface"] stage0 (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
```
After:
```
Testing {rustc_interface} stage0 (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
```
Note there is a slight consistency between `build` and `test`: The
former doesn't print "compiler artifacts". It would be annoying to fix
and doesn't hurt anything, so I left it be.
```
; x t rustc_interface --stage 0 --dry-run
Testing {rustc_interface} stage0 (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
; x b rustc_interface --stage 0 --dry-run
Building {rustc_interface} stage0 compiler artifacts (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
```

This mostly reverts 468acca108e65101b802821bded17149dc1d86c9, while still
fixing the problem it fixed by using an internal list-style-position. It
results in a slight change in the hover indicator, but nothing misleading.

rustdoc: remove redundant CSS `.source .content { overflow: visible }`
When added in 7669f04fb0ddc3d71a1fb44dc1c5c00a6564ae99 / #16066, the page itself was set to scroll. Now it's set so that the `example-wrap` is scrolling inside the page, so the overflow setting for the content is irrelevant.

The test was minified from the published `msf-ice:0.2.1` crate which failed in a crater run.
A faulty compiler was triggering a `higher-ranked lifetime error`:
> could not prove `[async block@...]: Send`

Respect --set=target.platform when building rustbuild itself
`--set=target.platform.cc` and `--set=target.platform.cxx` are ignored if target is quoted.
`--set=target.platform.linker` is ignored if RUSTFLAGS is not set.

Previously, clean only supported `--stage 0` for specific crates.
The new `crate_description` function generates a string that looks
like
```

rustdoc: simplify settings, help, and copy button CSS by not reusing
Since there remains only one common CSS rule shared between them, there's no point to it: the block and selector costs more than the single `width` rule saves.

Provide a better error and a suggestion for `Fn` traits with lifetime params
Given `Fn`-family traits with lifetime params in trait bounds like `fn f(_: impl Fn<'a>(&'a str) -> bool)`, we currently produce many unhelpful errors.
This PR allows these situations to suggest simply using Higher-Rank Trait Bounds like `for<'a> Fn(&'a str) -> bool`.
Fixes https://github.com/rust-lang/rust/issues/103490.

Bump rust-installer
`--without=component-a,component-b` now requires full component names. This fixes rust-lang/rust#105755 (rust-lang/rust-installer#119).
dev-static build succeeded, and installer script seems to work (see comment in thread).

update Miri
Main PRs:

- https://github.com/rust-lang/miri/pull/2744
This should help quite a bit with Miri support for less common targets. :)
