UefiCpuPkg/PiSmmCpuDxeSmm: Add a new mIsShadowStack flag
This patch is code refactoring and doesn't change any functionality.
Add a new mIsShadowStack flag to identify whether current memory is
shadow stack. Previous smm code logic regards a RO range as shadow
stack and set the dirty bit in corresponding page table entry if
mInternalCr3 is not 0, which may be confusing.
