rust: sync: atomic: Add performance-optimal Flag type for atomic booleans
Add AtomicFlag type for boolean flags.
Document when AtomicFlag is generally preferable to Atomic<bool>: in
particular, when RMW operations such as xchg()/cmpxchg() may be used
and minimizing memory usage is not the top priority. On some
architectures without byte-sized RMW instructions, Atomic<bool> can be
slower for RMW operations.
