  rust: sync: Inline various lock related methods (2026-01-10 10:53:46 +0800)

----------------------------------------------------------------
Rust synchronization changes for v7.0:

- Add support for Atomic<i8/i16/bool> and replace most Rust native AtomicBool
  usages with Atomic<bool>, and further switching will require Atomic<Flag>
- Clean up LockClassKey and improve its docs
- Add missing Send and Sync trait impl for SetOnce
- Make ARef Unpin as it is supposed to be
- Add __rust_helper to a few Rust helpers as a preparation for helper LTO
- Inline various lock related functions to avoid additional function calls.
