JoltPhysics3D: Rework RigidBody wrapper

- Add a clear way to setup dynamic/kinematic or static bodies
- Body registration to the world is batched (all bodies created before a physics step are added together, which is what Jolt is optimized for)
- Added support for empty shapes (= rigid bodies without collision) using a very small shape and tagging the body as sensor
