Rollup merge of #128873 - ChrisDenton:windows-targets, r=Mark-Simulacrum
Add windows-targets crate to std's sysroot

With this PR, when backtrace is used as a crate from crates.io it will (once updated) use the real [windows-targets](https://crates.io/crates/windows-targets) crate. But when used from std it'll use std's replacement version.

This allows sharing our customized `windows_tagets::link!` macro between std proper and the backtrace crate when used as part of std, ensuring a consistent linking story. This will be especially important once we move to using [`raw-dylib`](https://doc.rust-lang.org/reference/items/external-blocks.html#dylib-versus-raw-dylib) by default.

Rollup merge of #128745 - dtolnay:spawnunchecked, r=workingjubilee
Remove unused lifetime parameter from spawn_unchecked

Amanieu caught this when reviewing the stabilization proposal in https://github.com/rust-lang/rust/issues/55132.

The `'a` lifetime here is useless. The signature is asking the caller of `spawn_unchecked` to "give me any lifetime that is shorter than your F's and T's lifetime", which they can always to with no effect, because arbitrarily short lifetimes exist.

std: refactor UNIX random data generation

This PR makes a number of changes to the UNIX randomness implementation:
* Use `io::Error` for centralized error handling
* Move the file-fallback logic out of the `getrandom`-specific module
* Stop redefining the syscalls on macOS and DragonFly, they have appeared in `libc`
* Add a `OnceLock` to cache the random device file descriptor

std: do not overwrite style in `get_backtrace_style`

If another thread calls `set_backtrace_style` while a `get_backtrace_style` is reading the environment variables, `get_backtrace_style` will overwrite the value. Use an atomic CAS to avoid this.

Trivial grammar fix in const keyword docs

This PR makes a trivial fix to the wording of a sentence in the `const` keyword docs.

> `const` items looks remarkably similar to `static` items, [...]

Either this should be written as
> A `const` items looks remarkably similar to a `static` item, [...]

or "looks" should be changed to "look".

I have selected the smaller diff.

Add `f16` and `f128` math functions

This adds intrinsics and math functions for `f16` and `f128` floating point types. Support is quite limited and some things are broken so tests don't run on many platforms, but this provides a starting point.

PinCoerceUnsized trait into core

cc ``@Darksonn`` ``@wedsonaf`` ``@ojeda``

This is a PR to introduce a `PinCoerceUnsized` trait in order to make trait impls generated by the proc-macro `#[derive(SmartPointer)]`, proposed by [RFC](e17e19ac7a/text/3621-derive-smart-pointer.md (pincoerceunsized-1)), sound. There you may find explanation, justification and discussion about the alternatives.

Note that we do not seek stabilization of this `PinCoerceUnsized` trait in the near future. The stabilisation of this trait does not block the eventual stabilization process of the `#[derive(SmartPointer)]` macro. Ideally, use of `DerefPure` is more preferrable except this will actually constitute a breaking change. `PinCoerceUnsized` emerges as a solution to the said soundness hole while avoiding the breaking change. More details on the `DerefPure` option have been described in this [section](e17e19ac7a/text/3621-derive-smart-pointer.md (derefpure)) of the RFC linked above.

Earlier discussion can be found in this [Zulip stream](https://rust-lang.zulipchat.com/#narrow/stream/136281-t-opsem/topic/Pin.20and.20soundness.20of.20unsizing.20coercions) and [rust-for-linux thread](https://rust-lang.zulipchat.com/#narrow/stream/425075-rust-for-linux/topic/.23.5Bderive.28SmartPointer.29.5D.20and.20pin.20unsoundness.20rfc.233621).
