Beat Küng 5dff065ec5 uavcan: move to work queue and use MixingOutput
Main UAVCAN protocol handling and ESC updates run on the same thread/wq as
before. There are 2 WorkItems for separate scheduling of the 2, so that
ESC updates run in sync with actuator_control updates. UAVCAN is scheduled
at a fixed rate of 3ms (previously the poll timeout) and on each UAVCAN
bus event.
This leads to roughly the same behavior as before. CPU & RAM usage are
pretty much the same (tested on Pixhawk 4).

Testing done: Motors still work (with feedback), param changes and a
UAVCAN optical flow sensor.
