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.
