BTS used DS save area by IA32_DS_AREA MSR to get invoker IP instead of the
Last Branch Record Stack. So, removed the unnecessary BTS MSRs.

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.
