UefiCpuPkg: Extend SMM CPU Service with rendezvous support.
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.
