MdePkg/SynchronizationLib: fix Interlocked[De|In]crement return value

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1197

Today's InterlockedIncrement()/InterlockedDecrement() guarantees to
perform atomic increment/decrement but doesn't guarantee the return
value equals to the new value.

The patch fixes the behavior to use "XADD" instruction to guarantee
the return value equals to the new value.

The patch calls intrinsic functions for MSVC tool chain, calls the
NASM implementation for INTEL tool chain and calls GCC inline
assembly implementation (GccInline.c) for GCC tool chain.
