MdePkg/BaseSynchronizationLib: Add volatile Interlocked*() APIs
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.
