Deprecate atomic::spin_loop_hint in favour of hint::spin_loop
For https://github.com/rust-lang/rust/issues/55002
We wanted to leave `atomic::spin_loop_hint` alone when stabilizing `hint::spin_loop` so folks had some time to migrate. This now deprecates `atomic_spin_loop_hint`.

This was noticed while we were updating the embedded rust book: https://github.com/rust-embedded/book/pull/273/files
These targets do natively have atomic load/stores, but do not support CAS operations.

Revert adding Atomic::from_mut.
This reverts #74532 , which made too many assumptions about platforms, breaking some things.
Will need to be added later with a better way of gating on proper alignment, without hardcoding cfg(target_arch)s.

To be merged if fixing from_mut (#76965 ) takes too long.
