- set MAV_TYPE as a parameter default per vehicle type, or airframe if necessary
- cleanup MAV_TYPE param metadata and commander helper to only include
what's currently used in PX4
Remove params from airframe configs that are just set again
to the param default value or to the value that is
specified in the mc_default, fw_default or vtol_default.
