Restore Sodium's fast fog and sky-color sampling in affected Sodium and Iris combinations.

Solder is a small compatibility fix that reduces some rendering work when that optimization has been disabled. It needs no configuration and stays inactive when there is nothing to fix.

It is not a general FPS booster. Its effect depends on the particular Sodium and Iris releases you use.

The original optimization is Sodium's work. Sodium is by CaffeineMC; Iris is by the Iris Shaders team.
