UefiCpuPkg/CpuMpPei: Add GDT migration support (CVE-2019-11098)
...
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1614
Moves the GDT to permanent memory in a memory discovered
callback. This is done to ensure the GDT authenticated in
pre-memory is not fetched from outside a verified location
after the permanent memory transition.

UefiCpuPkg/CpuMpPei: fix vs2012 build error
...
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1166
Visual Studio 2012 will complain uninitialized variable, StackBase,
in the CpuPaging.c. This patch adds code to init it to zero and
ASSERT check against 0. This is enough since uninit case will only
happen during retrieving stack memory via gEfiHobMemoryAllocStackGuid.
But this HOB will always be created in advance.

UefiCpuPkg/CpuMpPei: support stack guard feature
...
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.
