MdePkg/BaseSynchronizationLib: Added proper support for ARM architecture

Browse Source 
This implements the following synchronization primitives for AArch64 (GCC)
and ARM (GCC & RVCT):

InternalSyncCompareExchange32
InternalSyncCompareExchange64
InternalSyncIncrement
InternalSyncDecrement

Note: these functions are implemented using the exclusive monitor,
which implies that they can only be used after the caches (and hence
the MMU) have been enabled.
