Subject: UefiCpuPkg: Build MpInfo2HOB in CpuMpPei

Build MpInfo2HOB in CpuMpPei module so that later
PiSmmCpuDxe or other StandaloneMm module can consume
the HOB.
Since there might be more one gMpInformationHobGuid2
in HOB list, CpuMpPei create a gMpInformationHobGuid2
with 0 value NumberOfProcessors field in the end of the
process to indicate it's the last MP_INFORMATION2_HOB.
