UefiCpuPkg/SmmCpuFeaturesLib: Add SMRR PhysBase/PhysMask fields check
SMRR range size and alignment should follow the rules like MTRR:
a. The minimum range size is 4 KBytes and the base address of the
range must be on at least a 4-KByte boundary.
b. For ranges greater than 4 KBytes, each range must be of length
2^n and its base address must be aligned on a 2^n boundary, where
n is a value equal to or greater than 12. The base-address
alignment value cannot be less than its length.
Thus, it could meet "Address_Within_Range AND PhysMask = PhysBase
AND PhysMask".
