Cycles: Fix uniform cone sampling This code is currently only used for the Glossy Toon BSDF, but it's a generic building block that might be used for other things in the future. To see why the current code does not give a uniform distribution, consider that it chooses both angles uniformly, but the smaller the angle from the center of the cone is, the smaller the differential solid angle is (similar to how sampling disks by choosing radius and phi uniformly does not work).
