[All] Clean collision detection in FreeMotionAnimationLoop

[bakpaul]

The inheritance link between CollisionResetVisitor and CollisionVisitor and some other had a consequence that ProcessGeometricalData was called multiple times in the FreeMotionAnimationLoop when the free motion and the collision detection where computed in parallel.

Another issue was that we had two time the timers for the substeps of the collision detection in the case of parallel computation : IMO only the AnimationLoop should have timers for global computation made by visitors. Here I remove the one of the Pipeline.
