MdeModulePkg/MmCommunication: add a physical address field to the comm buffer
Modify the definition of the MM communicate protocol so that the header
structure of the communication buffer contains a physical address field
that holds the physical address of the buffer itself. This permits
MM client code to be shared between traditional MM (that needs to know
the physical address of the buffer) and standalone MM (which needs the
virtual buffer address instead).
Since the SMM and MM versions of this protocol are now no longer identical,
also refresh its GUID.
