  1. StandaloneMmPkg: Add PeiStandaloneMmHobProductionLib 

    This is a NULL class library with a constructor that registers
notifications on data sources needed to produce HOBs consumed
within the Standalone MM core environment.

The data source must be a standard based API so the library
remains portable.

  2. TCBZ3398 and TCBZ3430: Make MessageLength the same size in EFI_MM_COM… 

    …MUNICATE_HEADER for both IA32 and X64

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3398
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3430

These changes update references to the MessageLength field of EFI_MM_COMMUNICATE_HEADER.
This structure can be used for both PEI and DXE MM communication. Thus, for
a system that supports PEI MM launch but operates PEI in 32bit mode and MM foundation in 64bit,
the current EFI_MM_COMMUNICATE_HEADER definition will cause structure parse error due to UINTN used.

  3. UefiCpuPkg: SmmCpuExceptionHandlerLib: Extend reloc flag to GCC 

    When building standalone MM core module, the relocation is also
disabled and this will introduce a linker break when this is done
with GCC.

Thus extending the flag to cover GCC builds as well.

  4. Implement MmServicesTableLib for MM Core (microsoft#730) 

    This change added the long vacant `MmServicesTableLib` for MM core instance.
The implementation will use extern to link the gMmst to the global MM table,
so that the libraries can use gMmst more generically.
