Fix: Cycles Principled BSDF specular component wrong IOR when backfacing
...
is visible when Transmission value is between 0 and 1.
The behaviour is actually not well defined for specular layer when
coming from inside, but this is at least consistent with the
transmission component and also consistent with the current behaviour in
OSL. Could probably save one closure allocation in svm later.

Use square root of the base color for transmission color
...
because the color is applied both on entrance and exit. Using square
root makes the resulted color closer to the base color.

Refactor: Cycles: weight reflection/refraction lobe selection pdf by tint

Now that there are different Fresnel types and the reflectance can be tinted,
it is better to sample based on the tinted instead of the real Fresnel. Also
avoid computing Fresnel multiple times.
