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.

When StackGuard is enabled, the CpuMp driver allocates
known good stacks for all CPUs for DF# and PF# exceptions.
It uses AllocatePool to do so.
The size needed equals to 64KB
= StackSize (2K) * ExceptionNumber (2) * NumberOfProcessors (16)
However, AllocatePool max allocation size is less than 64K.
To fix the issue, AllocatePages() is used.

This feature is the same as Stack Guard enabled in driver CpuDxe but
applies to PEI phase. Due to the specialty in PEI module dispatching,
this driver is changed to do the actual initialization in notify
callback of event gEfiPeiMemoryDiscoveredPpiGuid. This can let the
stack guard apply to as most PEI drivers as possible.
To let Stack Guard work, some simple page table management code are
introduced to setup Guard page at base of stack for each processor.
