UefiCpuPkg: Add ResetVector/FixupVtf

This implements the older VTF ResetVector code often used on EDK II
IA32 & X64 platforms.

This VTF requires build time fixups in order to find the SEC entry
point. The BaseTools GenFv tool has code that patches the jump target
of the reset vector code to match the entry point of the SEC image in
the PEI Firmware Volume.

v2:
 * Rename from OldVtf to FixupVtf
 * Use EDK II extension of .nasmb rather than .nasmbin
