This patch set is to use CpuPageTableLib to create and update smm page table.
With the CpuPageTableLib, we can create or update page table by calling
PageTableMap() in CpuPageTableLib multiple times. Then the original page table
manipulating code can be removed.

Dun Tan (7):
  UefiCpuPkg: Use CpuPageTableLib to convert SMM paging attribute.
  UefiCpuPkg/PiSmmCpuDxeSmm: Avoid setting non-present range to RO/NX
  UefiCpuPkg: Extern mSmmShadowStackSize in PiSmmCpuDxeSmm.h
  UefiCpuPkg: Refinement to current smm page table generation code
  UefiCpuPkg: Add SortLib required by PiSmmCpuDxe in DSC
  UefiCpuPkg: Refinement to code about updating smm page table
  UefiCpuPkg/PiSmmCpuDxeSmm: Remove unnecessary function
