MdeModulePkg-MemoryProfile(1): Add SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET definition.
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.
