AP_NavEKF3: improved core comparison to check alignment
...
this adds coreBetterScore() which takes account of tilt and yaw
alignment when comparing cores for lane switching
this ensures we don't switch to a lane that is unaligned due to the
zero error score for unaligned lanes

AP_NavEKF3: implement sensor affinity using EK3_AFFINITY parameter
...
this allows the EKF core index to be used to select a GPS/baro/mag
instance. This is an alternative to GPS blending that allows EKF lane
switching to be used to select the right combination of GPS and IMU
