* VW MQB: Cleanup and abstractions

* regen CARS.md

* Update selfdrive/car/volkswagen/values.py

Co-authored-by: Adeeb Shihadeh <adeebshihadeh@gmail.com>

* regen CARS.md

* now that's a refactor of a different sort

* move shifter value init/storage

 <sup>7</sup>Model-years 2021 and beyond may have a new camera harness design, which isn't yet available from the comma store. Before ordering, remove the Lane Assist camera cover and check to see if the connector is black (older design) or light brown (newer design). In the interim, if your car has a J533 connector CAN gateway inside the dashboard, choose "VW J533 Development" from the vehicle drop-down for a suitable harness. (Some newer models are also observed to not have a J533 connector.) <br />
