UefiCpuPkg:Relocate AP to new safe buffer in PeiMpLib

In this commit, change PeiMpLib to install callback
of gEdkiiEndOfS3ResumeGuid to relocate AP to new safe
buffer. The gEdkiiEndOfS3ResumeGuid is installed in
S3Resume.c before jmping to OS waking vector.

Previously, code in CpuS3.c of PiSmmCpuDxe driver will
prepare the new safe buffer for AP and place AP in hlt
loop state. With this code change, we can remove the
Machine Instructions of mApHltLoopCode in PiSmmCpuDxe.
Also we can reuse the related code in DxeMpLib for
PeiMpLib.
