Oliver Smith-Denny f0390f7bf1 UefiCpuPkg: Make the ResetVector USER_DEFINED 
The x86 reset vector is the initial FW code to run on an
AP. It should not link to any libraries and is implemented
entirely in assembly. This module is currently labled as
SEC, because it runs during the SEC phase, but by having it
SEC, it will be linked to all NULL libraries linked globally.
This causes issue with StackCheckLib (though any NULL
library being applied globally has the same issue) because
BaseTools will attempt to link the library and add an
extern to _ModuleEntryPoint, which does not exist for this
module.

Moving this module to USER_DEFINED instructs BaseTools to
not link any NULL libraries to it, which is the desired
behavior, and leads to a much cleaner global NULL library
implementation, in this case for StackCheckLib.

This change was tested on OVMF IA32/X64 and proved to work
as before.

Jordan Justen 3449f56dac 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
