This new PCD is used to specify the AP C-state value by MWAIT instruction.
More deeper C-state means more longer latency time when APs exiting from MWAIT
state. Platforms need to balance the performance and power saving to find the
proper C-state for APs.
Also, some processor may not ready for the deepest C-state at the beginning.
Platform also could choose the proper chance to place AP into the deeper C-state
by set this PCD before hand-off to OS.

This new PCD is used to specify the AP loop mode during POST phase.
The value 1 means we will place AP in the Hlt-Loop state by HLT instruction.
BSP need to send INIT-SIPI-SIPI to wake up APs.
The value 2 means we will place AP in the deepest C-state by MWAIT instruction.
BSP need to modify the monitor buffer by MONITOR instruction to wake up APs.
The value 3 means we will place AP in the Run-loop state. APs are running.
BSP need to write one semaphore to wake up APs.

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.

5. Add PACKAGE_UNI_FILE UNI file that contains the localized Abstract and Description of a package and localized strings associated with PCDs.
a. Addresses an information gap between DEC files and the UEFI Distribution Packaging Specification XML schema
b. There will be an associated update to UPT in BaseTools to consume PACKAGE_UNI_FILE and associated UNI file during UDP creation that performs the DEC -> XML conversion.
c. There will be an associated update to UPT in BaseTools to produce PACKAGE_UNI_FILE and associated UNI file during UDP installation that performs the XML -> DEC conversion.
6. Add Package Extra UNI file that provides the localized Name of a package.
a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a package to specify extra files to be added to a UDP without having to list the files in the UPT package information data file.
b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation.
c. UNI file contains localized name of a package to go along with the localized Abstract and Description from the PACKAGE_UNI_FILE.
