add per pass options control in cycles (and eevee)

actually, we have no control on how passes are build by cycles and eevee, on filtering (closest, gaussian...), precision (half-float,float, int...), etc ... making some passes sometimes unusable. (like the uv pass, because of anti-aliasing) so we set a new render with different rendersettings. lot of work time/ disk space/rendering time is loosed

for more control and more usable passes in compositing, we need to control passes by group and independantly

I guess that arnold have the best way to handle it, as showed here : docs.arnoldrenderer.com/display/A5AFMUG/AOVs

3 dropdown menus next to the pass name can be really effective way to manage it
