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.

Roman BapstandThomas Stastny dd2322d622 Added PerformanceModel for fixed wing (#22091)
* created a Performance Model for fixed wing vehicle
- added compensation for maximum climbrate, minimum sinkrate, minimum airspeed and trim airspeed based on weight ratio and air density
- added atmosphere lib to standard atmosphere calculations

Daniel Agar 77baa7c24a ekf2: EKFGSF yaw estimator always run
- if not in air the accel noise is doubled
 - if landed don't init unless GPS velocity is non-negligible
 - when inactive continue seeding with EKF gyro bias
 - reset yaw estimator if GPS fusion is stopped

bresch a989e5338c ekf2: reset globlal position uncertainty when GNSS is fused
There is no reason to keep an uncertainty on the origin as it is then
already contained in the local position estimate when GNSS data is fused
in the filter.

bresch 10db6b6eda ekf2: remove sparse vector optimization
The sparse vector template requires to know which states are non-zero in
the observation jacobian. This complicates the modularity of the code
when the state vector or the derivation is changed.
The computation cost difference is almost negligible for this size.

bresch db97a38a9d ekf2 rng kin: allow check to become true during horizontal motion
Even if there is some horizontal motion, a passing check should be
accepted as the terrain can be flat. However, the vehicle must not be
moving horizontally to invalidate the consistency as a change in terrain
can make the kinematic check temporarily fail.
