bresch 9e2e888f5e ekf2-bias_cal: reduce required stability period
For the mag, 30s of bias learning is a lot, given that it is only active
during turns and that it usually converges in < 5 seconds

bresch 2f52926972 mag_cal: fix mag bias estimate to mag cal
- since last_us is set to 0 every time the bias is not observable, the
  total time was also reset -> needed 30 consecutive seconds in mag 3D
  to be declared "stable"
- after landing, the mag_aligned_in_flight flag is reset. Using this for
  bias validity makes it invalid before we have a chance to save it to
  the calibration.

bresch f5edff2647 ekf2 - preflt checks: scale flow innovation checks
Opt flow raw innovations can be really large on ground due to the small
distance to the ground (vel = flow / dist). To make the pre-flight check
more meaningful, scale it with the current distance.

Mathieu Bresciani 24de623989 EKF2: Zero gyro update (#21691)
When at rest, directly fuse the gyro data as an observation of its bias.
This allows to strongly observe the gyro biases without having to fuse a
constant heading that makes the ekf too confident about its heading.

bresch 17806a9608 ekf2: robustify wind init using airspeed
Tests showed that sideslip fusion often starts just before airspeed
fusion, resetting the wind states to 0 instead of using the airspeed
data. A quick look at the wind uncertainty allows to know if the current
wind estimate is meaningful or if we should rather reset it using the
airspeed data.

Silvan Fuhrer 98d07ad1f3 disable side slip fusion for tailsitters
The attitude frame is wrong for tailsitters doing side slip fusion for wind estimation.
It doesn't take into account that the frames is 90deg tilted in FW flight.
