MdeModulePkg: Add Standalone MM perf library support
Adds a new library instance to support logging performance data in Standalone MM. - Add StandaloneMmPerformanceLib instance - Move common MM logic to a new file `SmmPerformanceLibInternal.c` - Since the library largely defers most logic to the performance measurement protocol a large degree of code can be shared between Standalone MM and Traditional MM.
