MdeModulePkg-MemoryProfile(3): Use SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET in MemoryProfileInfo.

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.
