REF? https://bugzilla.tianocore.org/show_bug.cgi?id=3815 This patch define a new Protocol with the new services SmmWaitForAllProcessor(), which can be used by SMI handler to optionally wait for other APs to complete SMM rendezvous in relaxed AP mode. A new library SmmCpuRendezvousLib is provided to abstract the service into library API to simple SMI handler code.
