Rollup merge of #135684 - ranger-ross:mutex-docs, r=joboet
docs: Documented Send and Sync requirements for Mutex + MutexGuard

This an attempt to continue where #123225 left off.

I did some light clean up from the work done in that PR.
I also documented the `!Send` + `Sync` implementations for `MutexGuard` to the best of my knowledge.
Let me know if I got anything wrong 😄

fixes #122856
