Weizhen Huang 1284e98ab8 Cycles: use low-distortion mapping when sampling cone and hemisphere ...

based on concentric disk mapping.
Concentric disk mapping was already present, but not used everywhere.
Now `sample_cos_hemisphere()`, `sample_uniform_hemisphere()`, and
`sample_uniform_cone()` use concentric disk mapping.
This changes the noise in many test images.
