This patch enhance SMM memory profile SMM communication by using fixed SMM communication buffer.
A new command SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET is added, because we need to support get partial ProfileData to fixed SMM communication buffer. If profile data is bigger than fixed SMM communication buffer, the DXE agent need to call SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET multiple times to get all data out. This is designed to meet Microsoft WSMT table definition on FIXED_COMM_BUFFERS requirement.
