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.
