Cycles: Add thin film iridescence to Principled BSDF

WI think we could default to the IOR of water, which is 1.33.

Specify the unit (nm).

Why not sqrtf() here?

I believe we should trust fresnel_dielectric_polarized() instead of checking TIR before calling the function.

This function is almost identical as fresnel_dielectric() except for the phase computation, would it be practical to reuse that function? The phase computation could then be:

What is this TODO?
