MdePkg/BaseSynchronizationLib: Add spin lock alignment for IA32/x64
From Intel(R) 64 and IA-32 Architectures Software Developer's Manual, one lock
or semaphore is suggested to be present within a cache line. If the processors
are based on Intel NetBurst microarchitecture, two cache lines are suggested.
This could minimize the bus traffic required to service locks.
