Move EFI_SMM_COMMUNICATE_HEADER into SmmBase.h because this structure is really associated with the ComminicationBuffer parameter to the EFI_SMM_CALLBACK_ENTRY_POINT in the SMM Base Protocol and not the gSmmCommunicateHeaderGuid. This GUID is just one of many possible GUIDs that could be used to fill in the HeaderGuid field of the EFI_SMM_COMMUNICATE_HEADER.
