[PATCH v4 1/5] UefiCpuPkg/UefiCpuPkg.dec: Create FixedPCDs for SMM support

[Leo Duran <leo.duran@amd.com>]

Introduce a couple of FixedPCDs to replace Intel-specific macros.
The new PCDs will allow SMM support on AMD-based x86 systems.

1) PcdCpuSmmSmramSaveStateMapOffset - SMRAM Save State Map Offset.
2) PcdCpuSmmPSDOffset - Processor SMM Descriptor Offset in SMRAM.
