UEFI231 spec compliance:
UEFI231 defines EFI_SMM_COMMUNICATION_ACPI_TABLE. We should move it from Pi/ dir to Uefi/ dir.
UEFI231 defines EFI_SMM_COMMUNICATE_HEADER. We should move it from Protocol/SmmCommunication.h to Uefi/ dir.
The original file will still include the new data structure to keep compatibility.
