Fixed RigidBody stuttering when changing collision layer/mask

- Changing collision layer/mask now only updates the broadphase proxy to avoid the velocity to be reset each time (also avoids unnecessary computations)
- No rigid body update at all when the collision layer/mask stays the same
- Same changes for Area for optimization purpose

Fixes #32577
