backends/drm: properly handle neither CTM and gamma being supported

Instead of hardcoding only NVidia, try to use CTM and GAMMA_LUT before falling
back to the shader path. This way it also works on other GPUs that lack
color management hardware, and only falls back to the color management path
on older NVidia drivers.

This commit also ensures that the color management hardware is set properly
after toggling color management on and off again, and simplifies ColorDevice
to only deal with rgb factors instead of always calculating luts. This should
improve performance of night color animations on hardware where CTMs are
supported
