Paul Riseborough 91423d4c71 AP_NavEKF3: Remove unncessary local position height reporting offset 
The offset generated by the EK3_OGN_HGT_MASK parameter bit 2 option is applied to the baro or range finder sensor so it does not have to be applied to the local position height.

Peter Barker ce04d69d53 AP_NavEKF3: correct compilation in SITL when logging is disabled 
this code is gated on HAL_BOARD_SITL already, and usually we have logging in SITL.  But not always

Peter Barker 21edc6aee1 AP_NavEKF3: do not trust number of beacons to not change 
if the count from the beacon library changes we may end up looking at memory we shouldn't

Peter Barker a517d5fed1 AP_NavEKF3: correct initialisation of BeaconFusion data structure 
the fusionReport object is not being cleared when the filter undergoes a forced reset.

So delete and recreate the object.  Will also make this sensitive to the number of beacons changing.

Also don't attempt to allocate zero bytes.

Andrew Tridgell 484312df93 AP_NavEKF3: fixed race condition in updateFilterStatus() 
filter status was initially set to zero then updated. This interacts
with the IMU filtering code which checks filter status from a
different thread to determine active_EKF_type(). When the race
condition is hit then the IMU we are running notch filters on changes
for a single sample, causing a notch filter glitch

Andrew Tridgell d11d4fa0bf AP_NavEKF3: fixed velocity reset on AID_NONE 
The ResetVelocity() function is only supposed to reset XY states, not
Z state. Resetting the Z state for velocity results in a large
velocity glitch if a vehicle is descending or ascending when aiding
switches to AID_NONE

this fixes #19386

Peter Barker 35a5a73f52 AP_NavEKF3: avoid using struct Location 
clang reports this could be a problem when compiling under some EABIs.  Remove it from most places as it is just noise, replace with class where we want to avoid including Location.h

Peter Barker da95985dd7 AP_NavEKF3: remove mag_state state 
we don't need to persist this across multiple calls as we now fuse all axes on the one step.

I've moved the defintion of these variables to where they are initialised to make it clear they're not used uninitialised.
