Distance Scrambling for for Cycles X - Sobol version

Cycles:Distance Scrambling for Cycles Sobol Sampler

This option implements micro jittering an is based on the INRIA
research paper [[ https://hal.inria.fr/hal-01325702/document | on micro jittering ]]
and work by Lukas Stockner for implementing the scrambling distance.
It works by controlling the correlation between pixels by either using
a user supplied value or an adaptive algorithm to limit the maximum
deviation of the sample values between pixels.

This is a follow up of https://developer.blender.org/D12316
