Move all `sys::ext` modules to `os`
This PR moves all `sys::ext` modules to `os`, centralizing the location of all `os` code and simplifying the dependencies between `os` and `sys`.
Because this also removes all uses `cfg_if!` on publicly exported items, where after #81969 there were still a few left, this should properly work around https://github.com/rust-analyzer/rust-analyzer/issues/6038.

That PR caused multiple test failures when Rust's channel is changed
from nightly to anything else. The commit will have to be landed again
after the test suite is fixed.
Update RLS and Rustfmt
Closes#84537. Closes#84538.
I know there's https://github.com/rust-lang/rust/pull/82208 in progress but I'm not sure which we want to land first.
Also, I'm getting Rustfmt test failures due to inner attributes not permitted:

but let's see what CI says, first.

Deduplicate native libs before they are passed to the linker
Stop spamming the linker with the same native library over and over again, if they directly follow from each other. This would help prevent [this situation](https://github.com/MSxDOS/ntapi/issues/2).
Issue #38460 has been open since 2016 so I think it's worth making an incomplete fix that at least addresses the most common symptom and without otherwise changing how Rust handles native libs. This PR is intended to be easy to revert (if necessary) when a more permanent fix is implemented.
Retain data in vectorized registers for longer
This seems to be a mild performance improvement on the keccak crate at least, though not sure it'll show up more broadly.
Get rid of fake `DefId`s in rustdoc
Right now there are *many* errors left, but I wanted to show the current state since all that is left to do is fixing the errors.
Resolves#83183
r? `@jyn514`
When encountering a path that can't have generics, do not call
`generics_of`. This would happen when writing something like
`path::this_is_a_mod<const_val>`.
Fix#84831.
Valid underscores in hex/octal/binary literal docs
Currently hex/octal/binary literals with computed values are displayed like `0_xff_fff_fffu32`, which is invalid since underscores can't be in the middle of integer prefixes. This properly formats prefixed integers.
This causes [`std::u32::MAX`](https://doc.rust-lang.org/std/u32/constant.MAX.html) to be displayed as
```rust
pub const MAX: u32 = u32::MAX; // 0_xff_fff_fffu32
```
This PR changes it to be displayed as:
```rust
pub const MAX: u32 = u32::MAX; // 0xffff_ffffu32
```
