jgong5 097e25cbaf Add function comments and refine function parameter IN OUT.

jgong5 ff443d3ebd Use on-demand paging for CpuSaveStates read/write. It was measured about 200us for either read or write the PI CpuSaveStates to framework, ~400us in total on a platform with 80 CPUs with original for loop implementation. So with on-demand paging, if the framework SMI handler doesn’t read/write CpuSaveStates, ~400us will be saved. If the handler happens to use CpuSaveStates, there will be about 20us overhead for either read or write a page which contains 5 continuous CpuSaveStates.

rsun3 8edfbe027c Security enhancement to SMM Base thunk drivers: Framework SMM drivers can't be loaded after SMRAM is locked.

rsun3 33f30f1ee3 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.

rsun3 673c149801 Remove the implementation limitation in the SmmBaseHelper driver that it assumes the Framework SMM driver to be loaded has a copy in memory.

mdkinney e906eae4a5 Add [depex] on gEfiMpServiceProtocolGuid so the number of CPUs is known 
Add [depex] on gEfiSmmCpuIo2Protocol so we know that the SMM CPU I/O 2 Protocol in the PI SMST is valid

mdkinney a7932d9a1a Clean up module to use SMM CPU Save State Protocol definitions from IntelFrameworkPkg instead of duplicating definitions in this module.

rsun3 f76edcfd29 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.
