IntelFsp2Pkg: X64 compatible changes to support PEI in 64bit

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3893
1.Added EFIAPI to FspNotifyPhasePeimEntryPoint, SwapStack and
  PEI_CORE_ENTRY.
2.Treat both MAX_ADDRESS and MAX_UINT32 as invalid address for
  FSP global data in FspApiCallingCheck().
3.Changed AsmReadEsp to AsmReadStackPointer.
4.Changed the type of the return value of AsmReadStackPointer
  from UINT32 to UINTN.
5.Changed the type of TemporaryMemoryBase, PermenentMemoryBase
  and BootLoaderStack from UINT32 to UINTN.
6.Some type casting to pointers are UINT32. Changed them to
  UINTN to accommodate both IA32 and X64.
7.Corrected some typos.
