MdePkg/Include: Add volatile to SynchronizationLib parameters

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 class.  Update the library class
to consistently use volatile on all functions in this class.
