Make rustdoc output deterministic for UI tests
Closes https://github.com/rust-lang/rust/issues/76442 (hopefully, since it's non-deterministic I don't have a way to test).

rustdoc: Fix font CSS for crate lists
I had put it in the wrong file in #76126. This should fix it now. Thank
you to `@ollie27` for pointing this out!

`@rustbot` modify labels: T-rustdoc C-bug
`write` is ambiguous because there's also a macro called `write`.
Also removed unnecessary and potentially confusing link to a function in
its own docs.
Many developers use a dark theme with editors and IDEs, but this
typically doesn't extend to graphviz output.
When I bring up a MIR graphviz document, the white background is
strikingly bright. This new option changes the colors used for graphviz
output to work better in dark-themed UIs.

Add help note to unconstrained const parameter
Resolves#68366, since it is currently intended behaviour.
If demonstrating `T -> U` is injective, there should be an additional word that it is not **yet** supported.

Fix HashMap visualizers in Visual Studio (Code)
CDB (as used in unit tests) doesn't care that we're using static_cast between unrelated types (`u8*` to `tuple<$T1, $T2>*`).
Visual Studio & Visual Studio Code care. These should've been reinterpret_cast or C casts.
Credit to @petrochenkov per https://github.com/rust-lang/rust/issues/76352 for helping catch this.
### Testing
```cmd
x.py test --stage 1 src/tools/tidy
x.py test --stage 1 --build x86_64-pc-windows-msvc src\test\debuginfo

remove public visibility previously needed for rustfmt
`submod_path_from_attr` in rustc_expand::module was previously public because it was also consumed by rustfmt. However, we've done a bit of refactoring in rustfmt and no longer need to use this function.
This changes the visibility to the parent mod as was originally going to be done before the rustfmt dependency was realized (c189565edc (diff-cd1b379893bae95f7991d5a3f3c6d337R201))
We no longer lint assignments to const item fields in the
`temporary_assignment` lint, since this is now covered by the
`CONST_ITEM_MUTATION` lint.
Additionally, we `#![allow(const_item_mutation)]` in the
`borrow_interior_mutable_const.rs` test. Clippy UI tests are run with
`-D warnings`, which seems to cause builtin lints to prevent Clippy
lints from running.

The only link that I did not change is a link to a function on the
`pointer` primitive because intra-doc links for the `pointer` primitive
don't work yet (see #63351).
Add rust-dev component to support rustc development
This is preparatory work for permitting rustc developers to use CI-built LLVM rather than building it locally. Unlike distro-built LLVM, CI built LLVM is essentially guaranteed to behave perfectly for local development -- it is fully up to date, and carries all necessary patches.
This is a separate PR from #76349 because it needs to land before that one, since we want a master build with the full CI LLVM to be available for easier testing.
