UefiCpuPkg/PiSmmCpuDxeSmm: Remove mInternalCr3 in PiSmmCpuDxeSmm
This patch is code refactoring and doesn't change any functionality. Remove mInternalCr3 in PiSmmCpuDxe pagetable related code. In previous code, mInternalCr3 is used to pass address of page table which is different from Cr3 register in different level of SetMemoryAttributes function. Now remove it and pass the page table base address from the root function parameter to simplify the code logic.
