OvmfPkg: SmmCpuFeaturesLib: implement SMRAM state save map access
This implementation copies SMRAM state save map access from the
PiSmmCpuDxeSmm module.
The most notable change is:
- dropping support for EFI_SMM_SAVE_STATE_REGISTER_IO
- changing the implementation of EFI_SMM_SAVE_STATE_REGISTER_LMA to use
the SMM revision id instead of a local variable (which
UefiCpuPkg/PiSmmCpuDxeSmm/PiSmmCpuDxeSmm.c initializes from CPUID's LM
bit). This accounts for QEMU's implementation of x86_64, which always
uses revision 0x20064 even if the LM bit is zero.
