EEVEE: GGX: Use distribution of visible normal for sampling
This changes the sampling routine to use the method described in
"A Simpler and Exact Sampling Routine for the GGXDistribution of Visible Normals"
by Eric Heitz.
http://jcgt.org/published/0007/04/01/slides.pdf
This avoids generating bad rays and thus improve noise level in screen-
space reflections / refraction.
