SecurityPkg: Tcg2PhysicalPresenceLib: Introduce StandaloneMm instance

This change added a new instance of Tcg2PhysicalPresenceLib to support
MM_STANDALONE type drivers. It centralizes the common routines into
shared files and abstract the library constructor into corresponding
files to implement each constructor function prototypes.
