This removes the confusing ugly magic number of 233 introduced as part
of https://github.com/PX4/Firmware/pull/7670.

Also, the convoluted if is cleaned up using 3 separate bools with some
comments to explain what's going on.

This should not change anything function-wise except that the flight
controller could now potentially also use system ID 233 and not break
forwarding.

tiltrotor: fix transition check when airspeed is invalid

Needed a clear scope inside a case for irlock_reports.

- the stackcheck build is too slow to be useful
- will be recreated with fmu-v5

Support Emlid Reach in ERB format,
including autodetect

The behaviour is unchanged because VT_ELEV_MC_LOCK was not implemented for tiltrotors
