UefiCpuPkg VTF0 X64: Build page tables in NASM code

UefiCpuPkg VTF0 X64: Build page tables in NASM code

Previously, we would build the page tables in
Tools/FixupForRawSection.py.

In order to let NASM build VTF0 from source during the EDK II build
process, we need to move this into the VTF0 NASM code.
