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

Update MemoryProfileInfo APP to use fixed SMM communication buffer to get
profile data by SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET API.

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