Volkswagen safety updates: Phase 1 (#444)

* Checkpoint Panda refactoring updates

* Rename MQB safety tests in preparation for PQ

* Refactor MQB tests, add missing torque test

* Bring in MQB init without CRC LUT setup

* Fix to ACC_06 test case

* Fix to ACC_06 test case

* Tweak comment for clarity

* Drop superfluous return
