NumberOfCpus and SmmStartupThisAp field in Framework SMST should be updated per PI SMST at SMM runtime context. These two fields in PI SMST are not guaranteed to be valid at SMM initialization phase.

Fix bugs in SmmBaseHelper driver.

1. Should use sizeof(EFI_SMM_CPU_SAVE_STATE) instead of sizeof (EFI_SMI_CPU_SAVE_STATE) to allocate buffer for CpuSaveState in Framework SMST;
2. The type of Width parameter for ReadSaveState() and WriteSaveState() functions of SMM CPU Protocol is UINTN instead of an enumeration type.
