REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3185 This change added support of SMI handler profile library router under StandaloneMm. This change replaces gSmst with gMmst. It also abstracts standalone and traditional MM driver entrypoints into separate files to allow maximal common implementations.
