Daniel Agar 4cb293020a ekf2: remove sensor sample uORB::Subscription missed perf counters
- these served their purpose, but are no longer useful
 - still worth keeping the IMU subscription missed perf count to catch any scheduling issues

bresch 1c3a1183c8 ekf2-flow: refactor control logic
Use flow rates instead of integrals in backend. This allows us to delay
the data to the mitpoint integration time and simplifies the code in
general.
Gyro compensation can still be done in EKF2 if needed, but the
flow module normally already appends the correct gyro data to the flow
message.

Daniel Agar 62027b0965 ekf2: remove EKF2_HGT_MODE VerifyParams() transition helpers
- in theory these are helpful to ensure EKF2_HGT_MODE configuration is
   consistent with the relevant aid source (GPS, baro, etc), but it can
   be a little awkward with users having to fight manual parameter
   changes in the right order

We should otherwise call this publication before the aid_src publisher

bresch 0aa4afdbce ekf2: add unaided_yaw for more resilient yaw control
This estimate doesn't converge to the true yaw but can be used as a
more consistent but drifting heading source.
It can be used by a setpoint generator to adjust its heading setpoint
while the true yaw estimate is converging in order to keep a constant
course over ground.

Mathieu Bresciani 74a54b3b12 EKF2: improve resilience against incorrect mag data
- when GNSS is used require low mag heading innovations during
  horizontal acceleration (yaw observable) to validate the mag
- only fuse mag heading just enough to constrain the yaw estimate
  variance to a sane value. Leave enough uncertainty to allow for a
  correction when the yaw is observable through GNSS fusion

Daniel Agar d75bb62a65 ekf2: separate mag and mag heading control logic (#21212)
- split mag_3d into new standalone mag fusion and mag fusion allowed to update all states (full mag_3d)
 - new dedicated control logic for mag/mag_3d fusion and standalone mag heading fusion
 - if WMM available use for mag_I and mag_B init
 - mag states reset if external yaw reset (yaw estimator, GPS yaw, etc)
 - mag reset if declination changed (eliminate _mag_yaw_reset_req)
 - mag fusion (but not mag_hdg or mag_3d) can be active during gps_yaw or ev_yaw (if yaw aligned north)

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.
