cuda cloth and collision operator

[tyFlow]

The CCCS is sort of its own thing, that is part of the post-operator solve. So it doesn't contribute to collision tests (you can't move particles between events based on whether or not they underwent collisions during the CCCS solve), and you can't exclude parts of the cloth from the CCCS once you enable the CCCS on the cloth. The only exception to the latter is if you disable those particles with a Particle Switch operator...but then they won't undergo any cloth solve.
