This change brings back old original logic which was checking whether worker threads do fit into an active CPU group. But it does it a bit smarter now and is also checking affinity within that group. This way Cycles will use all threads on a Threadripper2 CPU if it's set to automatic number of threads, but on another hand will not change affinity if user requested 16 threads and changed Blender affinity.
