StandaloneMmPkg: Add gMmStatusCodeUseSerialHobGuid HOB definition

Browse Source 
PcdStatusCodeUseSerial can be the dynamic PCD, which can't be used
in MM drivers. So, defines gMmStatusCodeUseSerialHobGuid HOB to
indicate StatusCode is reported via serial port or not. The value
shall match with the PcdStatusCodeUseSerial.
