MdeModulePkg-MemoryProfile(2): Add SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET in PiSmmCore. 

This patch enhance SMM memory profile SMM communication by using fixed
SMM communication buffer.

Update PiSmmCore to handle SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET
request.

This is designed to meet Microsoft WSMT table definition on FIXED_COMM_BUFFERS
requirement.
