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. (Sync patch r18645 from main trunk.)
