Fix OptiX viewport denoising not working when rendering scene (without OptiX) that uses unsupported features

Denoising devices do not need to load the full feature set of kernels, so only activate the denoising
feature for them (so that it is possible to use features that are supported by the render devices, but
not the denoising devices).
