rust: helpers: Add i8/i16 atomic try_cmpxchg_acquire helpers

Browse Source 
Add i8/i16 atomic try_cmpxchg_acquire helpers that call
try_cmpxchg_acquire() macro implementing atomic try_cmpxchg_acquire
using architecture-specific instructions.

[boqun: Use try_cmpxchg_acquire() instead of raw_try_cmpxchg_acquire()]
