EKF: Don't try to fuse air data if not in normal aiding mode
...
Taking off before passing GPS checks would cause airspeed or sideslip to be fused when the filter was still using a constant position assumption. This would cause large airspeed innovations, invalid wind estimates and degrade filter performance after GPS was gained and position and velocity was reset.

EKF: fix bug in sideslip fusion and reduce RAM usage
...
The bug meant the Y velocity (state index 5) covariance was not being updated correctly when sideslip was being used to constrain velocity drift (extended GPS loss).
The rework of the covariance update to reduce RAM follows the same pattern as adopted for other fusion processes

EKF: Improve wind state reset logic
...
Enables wind estimation without an airspeed sensor and enables synthetic sideslip to be used with an airspeed sensor for improved wind state estimation.
Wind states and covariances are reset differently depending on whether airspeed is available.

EKF: remove Ekf::KHP and move KHP to the methods where it's used
...
Everywhere where KHP is used, it is first completely reset, thus making
it unnecessary to keep it as a class member.
This saves 2.3KB RAM.
Stack sizes don't need changing, since there is already a function
Ekf::predictCovariance(), which needs around 3KB of stack and is called
close to where the fuse* functions are called.
