1. Add two performance measurement points for SMM performance measurement;
2. Introduce SmmCorePlatformHookLib library class defining two platform hook points. Update PI Smm Core to call the hook points before and after invoking registered SMI handlers. A NULL instance of this library class is implemented.
Note that after this check in, DSC files consuming the PiSmmCore.inf need to be updated to add a library instance for SmmCorePlatformHookLib library class.
