Add gEdkiiS3SmmInitDoneGuid, after S3 SMM initialization is done and before S3 boot script is executed, this GUID is installed as PPI in PEI and protocol in SMM environment. It allows for PEIMs or SMM drivers to hook this point and do the required tasks.
S3Resume will install the PPI and signal to SMM by communication, and then PiSmmCore will install the protocol.
