arch/x86: Add common assembly code for stages that run in CAR

This adds a few assembly lines that are generic enough to be shared
    between romstage and verstage that are ran in CAR. The GDT reload
    is bypassed and the stack is reloaded with the CAR stack defined
    in car.ld. The entry point for all those stages is car_stage_entry().
