fix test by reducing the distance to the new origin: the maximum size of
the local position origin is a cube of 1e6m. If the origin is moved
further than this, the state is clipped to that maximum value
Navigator sets the cruise_speed to -1 if the controller shouldn't listen to
it and instead use the default speed (for MC: MPC_XY_CRUISE). This is for
example for RTL the case, where we want to return at the default speed,
independetly of what the mission speed before was.

- synthetic airspeed will only be declared valid as soon as the wind variance
has dropped below a parameterized threshold. This is useful for vehicles without
an airspeed sensor which rely on synthetic airspeed but only once the vehicle
has turned sufficiently for the wind estimates to be reliable.

rtl state was getting reset on inactive, which meant that the state which triggered resuming e.g. mission landing would be overwritten, and the navigator mode would switch back and forth between rtl and mission. this commit:
1. moves the reset of rtl state to the on activation function (removing it from the on inactive function)
2. functionalizes the rtl state input to the rtl time estimator so that rtl time can still be calculated from state=none while inactive
This commit removes the additional airspeed check (airspeed for VTOLs in
hover below LNDFW_AIRSPD_MAX), as it is not a required condition in the
landed state (headwind blowing into the airspeed sensor won't stop
once on the gruond). In FW mode the check would make more sense, but there
the land detector is currently simply disabled.

- if using multi-EKF across all magnetometers then an instance of
vehicle_magnetometer is advertised immediately for every sensor_mag
instance
- this can become problematic if EKF2 multi-mag is enabled, but with
only 1 IMU (EKF2_MULTI_MAG) because you will be stuck with no magnetometer data
FW_LND_USETER defaulted to 1 and FW_LND_ABORT terrain based bits all enabled. why? because using a distance sensor is critical to detecting when to flare, and we want to force the user to actively disable these safety settings if they so choose, so that they understand the implications.
- new param, FW_LND_TER_REL
- fixing the glide slope helps keep the landing glide behavior steady (avoiding bumps in the altitude setpoint from e.g. trees)
- flare is still triggered via the distance sensor, if enabled by FW_LND_USETERR
when the vehicle did not track the slope well (e.g. at an offset above the track) and the altitude setpoint flattening on intersection with terrain, the throttle would spool up to smoothly intersect the newly flattened altitude setpoint, this could happen before the flare altitude was reached, which is bad. now the steady state glide behavior will be maintained, and flare can trigger at the appropriate time
