rust: lock: add trylock method support for lock backend
Add a non-blocking trylock method to lock backend interface, mutex and
spinlock implementations. It includes a C helper for spin_trylock.
Rust Binder will use this method together with the new shrinker
abstractions to avoid deadlocks in the memory shrinker.
