Parallelize tactile sensor computation.
...
The computation of tactile sensor values for each taxel is now parallelized using the MuJoCo threadpool when the number of taxels exceeds a threshold. Each thread processes a batch of taxels, accumulating forces from all colliding geoms.

See [documentation](https://mujoco.readthedocs.io/en/latest//modeling.html#actuator-force-clamping ) for justification and use cases.
- Add simple car model to `model/`.
- Move actuation-related test models into `engine/testdata/actuation/`.
