Fix D_GGX code which can cause divide-by-zero val
When given roughness is lower than 0.01, d value in original code will
be zero. This can make last return value as NAN because of
divide-by-zero. This is well addressed in issue #56373.
Modified code is referenced on D_GGX function of google/filament
(https://github.com/google/filament/blob/main/shaders/src/brdf.fs#L54-L79)
