Cycles: Clean up the Principled Hair BSDF implementation

Done: bb9eb262d4

I'll put together a quick workaround for #104586 that we can commit in the meantime.

Hm, this is a tricky one.

The problem here is that previously, the Principled Hair BSDF didn't write its color into the color passes at all, so there was no issue. Since that commit, the…

Light linking

@homspau I don't think doing the object-based approach where you get a output based on the sampled light is possible, due to the order in which the path is traced. The evaluation of the object's…

Cycles: Use per-microfacet Fresnel term for Glass closures

I've updated the BSDF sampling code to use a 3D sampler now. The third dimension is used (and rescaled afterwards) to pick the closure, most BSDFs still only use the first two dimensions but Glass…
