Li, Zhihao 4a68176cb5 UefiCpuPkg: Extend SMM CPU Service with rendezvous support.
REF? https://bugzilla.tianocore.org/show_bug.cgi?id=3815

This patch define a new Protocol with the new services
SmmWaitForAllProcessor(), which can be used by SMI handler
to optionally wait for other APs to complete SMM rendezvous in
relaxed AP mode.

A new library SmmCpuRendezvousLib is provided to abstract the service
into library API to simple SMI handler code.

Jeff Fan 262128e5ab UefiCpuPkg/LocalApicLib: Rename GetProcessorLocation()
GetProcessorLocation() is too generic and will conflict with the API defined in
Galileo Board Software Package v1.0.0.

This update is just to rename GetProcessorLocation() to one specific name
GetProcessorLocationByApicId().

Michael Kinney 529a5a8609 UefiCpuPkg: Add PiSmmCpuDxeSmm module no IA32/X64 files
Add module that initializes a CPU for the SMM environment and
installs the first level SMI handler.  This module along with the
SMM IPL and SMM Core provide the services required for
DXE_SMM_DRIVERS to register hardware and software SMI handlers.

CPU specific features are abstracted through the SmmCpuFeaturesLib

Platform specific features are abstracted through the
SmmCpuPlatformHookLib

Several PCDs are added to enable/disable features and configure
settings for the PiSmmCpuDxeSmm module

Changes between [PATCH v1] and [PATCH v2]:
1) Swap PTE init order for QEMU compatibility.
   Current PTE initialization algorithm works on HW but breaks QEMU
   emulator.  Update the PTE initialization order to be compatible
   with both.
2) Update comment block that describes 32KB SMBASE alignment requirement
   to match contents of Intel(R) 64 and IA-32 Architectures Software
   Developer's Manual
3) Remove BUGBUG comment and call to ClearSmi() that is not required.
   SMI should be cleared by root SMI handler.
