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.
