Subject: 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.
