Fix rust.css fonts.
The `rust.css` file (used for all non-rustdoc and non-mdbook pages) has gotten out of sync with rustdoc's css. The two share the same fonts, so this updates them to match what rustdoc uses.
It would be ideal not to need this at all, but that's for another time.
Fix CI to fetch master on beta channel
This forward-ports a fix from the beta channel (landing in #86413, hopefully) to master so that we don't need to apply it on each round of backports.
This bug also demonstrates that our channel-checking is a bit insufficient -- stable is checked, but beta has some of its own peculiarities currently and isn't checked. But this does not attempt to adjust for that; we likely can't afford to run both beta and stable channels by CI and the current state here seems OK for now.

rustfmt: load nested out-of-line mods correctly
This should address https://github.com/rust-lang/rustfmt/issues/4874
r? `@Mark-Simulacrum`
Decided to make the change directly in tree here for expediency/to minimize any potential backporting issues, and because there's some subtree sync items I need to get resolved before pulling from r-l/rustfmt
Rustfix update
This updates to rustfix 0.6.0. One of the key changes here is https://github.com/rust-lang/rustfix/pull/195 which changes rustfix to apply multi-part suggestions. One of the tests needs to updated because there are some overlapping suggestions which rustfix cannot handle. The solution is to only apply the machine-applicable suggestions to avoid the overlapping issue.
This also includes a minor change to compiletest to provide better error messages with rustfix.
Use Tera templates for rustdoc.
Replaces a format!() call in layout::render with a template
expansion. Introduces a `templates` field in SharedContext so parts
of rustdoc can share pre-rendered templates.
This currently builds in a copy of the single template available, like
with static files. However, future work can make this live-loadable with
a perma-unstable flag, to make rustdoc developers' work easier.
Part of #84419.
Demo at https://hoffman-andrews.com/rust/tera/std/string/struct.String.html.
Emit warnings for unused fields in custom targets.
Add a warning which lists any fields in a custom target `json` file that aren't used. Currently unrecognized fields are ignored so, for example, a typo in the `json` will silently produce a target which isn't the one intended.

Do not emit alloca for ZST locals with multiple assignments
This extends 35566bfd7d to additionally stop emitting unnecessary allocas for zero sized locals that are assigned multiple times.
When rebuilding the standard library with `-Zbuild-std` this reduces the number of locals that require an allocation from 62315 to 61767.

fix panic-safety in specialized Zip::next_back
This was unsound since a panic in a.next_back() would result in the
length not being updated which would then lead to the same element
being revisited in the side-effect preserving code.
fixes#86443
Fix a bug in the linkchecker
There was a small typo in the linkchecker (in #85652) that caused it to report a `#` fragment link error pointing to the wrong file (it was displaying the path to the source file, not the target of the link).
This also includes a few other changes:
- Fixes the tests due to some changes in the redirect handling in #84703.
- Adds the tests to rustbuild to run whenever the linkchecker itself is run.
- Updates the tests to validate more of the output (so that a mistake like this would have been caught).
Closes#86144
Lazify is_really_default condition in the RustdocGUI bootstrap step
The `RustdocGUI::should_run` condition spawns `npm list` several times which adds up to seconds of wall-time.
Evaluate the condition lazily to to keep `./x.py test tidy` and similar short-running tasks fast.
Fixes#86147
BTree: encapsulate LeafRange better & some debug asserts
Looking at iterators again, I think #81937 didn't house enough code in `LeafRange`. Moving the API boundary a little makes things more local in navigate.rs and less complicated in map.rs.

Replace some `std::iter::repeat` with `str::repeat`
I noticed that there were some instances where `std::iter::repeat` would be used to repeat a string or a char to take a specific count of it and then collect it into a `String` when `str::repeat` is actually much faster and better for that.

Move `OsStringExt` and `OsStrExt` to `std::os`
Moves the `OsStringExt` and `OsStrExt` traits and implementations from `sys_common` to `os`. `sys_common` is for abstractions over `sys` and shouldn't really contain publicly exported items.
This does introduce some duplication: the traits and implementations are now duplicated in `unix`, `wasi`, `hermit`, and `sgx`. However, I would argue that this duplication is no different to how something like `MetadataExt` is duplicated in `linux`, `vxworkx`, `redox`, `solaris` etc. The duplication also matches the fact that the traits on different platforms are technically distinct types: any platform is free to add it's own extra methods to the extension trait.
