There are cases where the default input passes of color+albedo do not yield useful results and while this was possible to change that for final frame rendering (in the layer settings), viewport denoising always used a fixed color+albedo. This adds an option to change the input passes for viewport denoising too, so that one can use it in scenes that otherwise wouldn't work well with it.
