Eliminate EFI_IMAGE_MACHINE_TYPE_SUPPORTED.
Move Gdt initialization from InitializeMpServiceData() to CPU Arch specific function.
We create SmmFuncsArch.c for hold CPU specific function, so that
EFI_IMAGE_MACHINE_TYPE_SUPPORTED(EFI_IMAGE_MACHINE_X64) can be removed.
For IA32 version, we always allocate new page for GDT entry, for easy maintenance.
For X64 version, we fixed TssBase in GDT entry to make sure TSS data is correct.
Remove TSS fixup for GDT in ASM file.
