MdeModulePkg/FirmwarePerfSmm:Enhance for new pref infrastructure 

V3:
a. Remove unused definitions
b. Get records size form the records buffer when getting size action
is triggered.

V2:
Update FirmwarePerformanceSmm to receive the address
of performance records instead of records content.

Receive buffer address of Boot performance records
which are reported by SmmCorePerformanceLib.
