UefiCpuPkg: Create gMpInformationHobGuid2 in UefiCpuPkg
Create gMpInformationHobGuid2 in UefiCpuPkg.
Currently, there is a gMpInformationHobGuid defined,
created and consumed only in StandaloneMmPkg. The HOB
contains the EFI_PROCESSOR_INFORMATION structure for
each CPU and the number of processors. This is the same
as the information that PiSmmCpuDxeSmm uses MpService
Protocol to get.
This new gMpInformationHobGuid2 also contains the
NumberOfProcessors and the EFI_PROCESSOR_INFORMATION
for each CPU. Also the HOB is extended to support the
case that the maximum HOB length is not enough for all
CPU. So there might be more than one HOB instance in the
HOB list. Each HOB describes the corresponding CPU index
range.
The plan is to create gMpInformationHob2Guid in CpuMpPei
module(implemented in next commit). Then PiSmmCpuDxeSmm
and other MM_STANDALONE modules can consume the hob. This
can avoid calling MpService Protocol in PiSmmCpuDxeSmm.
Also the issue that one gMpInformationHobGuid might be not
enough when CPU number is 1~2000 or bigger can be solved.

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.

UefiCpuPkg: Consume MpInfo2Hob in PiSmmCpuDxe
Consume MpInfo2Hob in PiSmmCpuDxe driver to get

EFI_PROCESSOR_INFORMATION for all CPU from the
MpInformation2 HOB.
This can avoid calling MP service.
