cpu/x86/64bit: Generate static page tables from an assembly file
This removes the need for a tool to generate simple identity pages.
Future patches will link this page table directly into the stages on
some platforms so having an assembly file makes a lot of sense.
This also optimizes the size of the page of each 4K page by placing
the PDPE_table below the PDE.
