SL-10478

Fix side-effects of having both sun and moon as potential directional light contributors.
We pass an int to the shader indicating which to prefer instead of making per-pixel decisions
and pass the moonlight color/di independently.

Obsolete llsettingssky fade color which was unused elsewhere and cached for no reason.
