BaseSynchronizationLib: Fix LoongArch64 synchronization functions
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4432
There is a return value bug:
The sc.w/sc.d instruction will destroy the reg_t0,
use reg_t1 to avoid context reg_t0 being corrupted.
Adjust Check that ptr align is UINT16.
Optimize function SyncIncrement and SyncDecrement.
