The nvidia role now handles full driver configuration instead of just
packages. Added options for open driver, modesetting, power management,
graphics settings, and driver package selection.
Updated zix790prors and wixos machine configs to use the new role
options, removing duplicated hardware.nvidia configuration blocks.
