This patch series add new SmmEndOfS3Resume event which required by some
SMM drivers.
It will implmented by SmmCore to install the gEdkiiSmmEndOfS3ResumeProtocolGuid
Protocol. Smm drivers can install this protocol's notification functions to
hoot this envet.
It will be trigged right after the EndOfPei event in S3 resume phase.
V2 Changes: Only change patch 2/3
1. Change structures name to avoid they start with EFI_.
2. Base on DXE phase bits to provide communication buffer, current implement
check both PEI and DXE phase.
