Andrew Tridgell c83e2d7c0e AP_NavEKF2: fixed loss of GPS fusion
we must not do a storedGPS.recall unless we will be using the data,
otherwise we will lose GPS samples and risk stopping GPS fusion

Paul Riseborough de0040ad69 AP_NavEKF2: Enable use of EKF-GSF yaw estimate
Enables the yaw to be reset in flight to a value estimated from a specialised yaw estimator. This allows faster recovery if taking off with a bad magnetometer and also allows yaw alignment and GPS use to commence in-air when operating without any yaw sensing.

Andrew Tridgell 414d3eb670 AP_NavEKF2: don't fuse GPS when EK2_GPS_TYPE=3
when using a vision position system, the user may have vision derived
GPS data coming in using GPS_INPUT msgs. We should not fuse these when
EK2_GPS_TYPE=3 as we end up fusing both vision data and GPS data,
which does not work with the current EK2 code

This change makes it possible to run EK2 and EK3 in parallel in a
Vicon, wityh EK2 using VISION_POSITION_ESTIMATE data and EK3 using
GPS_INPUT (with yaw) data.

Andrew Tridgell c57b25b4c9 AP_NavEKF2: ensure that EKF origin stays in sync on all cores
this prevents the EKF origin on different cores from being initialised
to different values. A common value is stored in the frontend and used
by a core if it doesn't have an origin

Andrew Tridgell 1c4c5a6850 AP_NavEKF2: learn gyro biases for inactive gyros
this allows us to learn the gyro biases each lane would need if it had
to switch to another gyro due to a sensor failure. This prevents a
sudden change in gyro bias on IMU failure
