Jordan Justen eee1d2ca90 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.

Jordan Justen a63f2e2450 UefiCpuPkg/ResetVector/Vtf0: Move Page Table/CR3 setting to a new file
Now, Transition32FlatTo64Flat calls SetCr3ForPageTables64
which is located in Ia32/PageTables64.asm.

This change is required so OVMF can replace the code in
Ia32/PageTables64.asm with code that generates page tables in
RAM.

Note: Since this change does not impact the functionality of the
current VTF0 binaries, they are not being updated. The resulting
new binaries were tested to verify there is no regression.
