Add Environment properties to control fog rendering on background sky

Browse source 
Values lower than 1.0 can be used to make the fog rendering not fully
obstruct the sky. This can be desired when using fog as a purely
atmospheric effect, without intending to use fog for open world fog
fading.

When set to 0.0, fog rendering behavior will be similar to Godot 3.x
where sky rendering was never affected by fog.
