Auto merge of #97791 - m-ou-se:const-locks, r=m-ou-se
Make {Mutex, Condvar, RwLock}::new() const.
This makes it possible to have `static M: Mutex<_> = Mutex::new(..);` 🎉
Our implementations [on Linux](https://github.com/rust-lang/rust/pull/95035), [on Windows](https://github.com/rust-lang/rust/pull/77380), and various BSDs and some tier 3 platforms have already been using a non-allocating const-constructible implementation. As of https://github.com/rust-lang/rust/pull/97647, the remaining platforms (most notably macOS) now have a const-constructible implementation as well. This means we can finally make these functions publicly const.
Tracking issue: https://github.com/rust-lang/rust/issues/93740
