03d8907321 UefiCpuPkg: Remove AMD 32-bit SMRAM save state map
Per AMD64 Architecture Programmer's Manual Volume 2: System
Programming - 10.2.3 SMRAM State-Save Area (Rev 24593), the AMD64
architecture does not use the legacy SMM state-save area format
(Table 10-2) for 32-bit SMRAM save state map. Clean up codes for the
invalid save state map.

b0d1cb59c7 UefiCpuPkg/AmdSmmCpuFeaturesLib: Skip SMBASE configuration
This patch is to avoid configure SMBASE if SmBase relocation has been
done. If gSmmBaseHobGuid found, means SmBase info has been relocated
and recorded in the SmBase array. No need to do the relocation in
SmmCpuFeaturesInitializeProcessor().

fbb6f18e1c UefiCpuPkg: Removes SmmCpuFeaturesReadSaveStateRegister
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4182

Removes SmmCpuFeaturesReadSaveStateRegister and
SmmCpuFeaturesWirteSaveStateRegister function from
SmmCpuFeaturesLib library.

MmSaveStateLib library replaces the functionality of the above
functions.
Platform old/new need to use MmSaveStateLib library to read/write save
state registers.
Current implementation supports Intel and AMD.
