MdePkg/BaseSynchronizationLib: Add volatile Interlocked*() APIs

Browse Source 
The SpinLock functions in the SynchronicationLib use volatile
parameters to keep compiler from optimizing these functions
too much.  The volatile keyword is missing from the Interlocked*()
functions in this same library instance.  Update the library instance
to consistently use volatile on all functions in the
SynchronizationLib class.
