Two sources:
1. global to local conversion was sometimes giving issues, so do everything in global
2. on startup the RTL didn't check if the home position was valid before processing it
-check for valid airspeed_validated (declared valid plus updated less than 1s ago)
-added param (COM_ARM_ARSP_EN) to enable/disable check for max airspeed for arming set max
airspeed limit to half of stall airspeed

- commander preflightcheck use estimator_sensor_bias message instead of EKF state index magic number
- ekf2 publish estimated bias limits in estimator_sensor_bias
- preflightcheck only error if bias estimate exceeds half of configured limit (delete COM_ARM_EKF_AB and COM_ARM_EKF_GB parameters)
- parameter updates can be quite expensive because they trigger nearly all modules to reload all of their parameters immediately
- limit modules from updating faster than once per second
- handle saving the mag bias per sensor (across all estimator instances using that mag) in sensors/vehicle_magnetometer
- this is now saving back to the actual mag calibration CAL_MAGn_OFF{X,Y,Z}
- ekf2 reset mag mag bias on any magnetometer or calibration change
- use Kalman filter scheme to update stored mag bias parameters using all available bias estimates for that sensor

The case when acceleration setpoints were being passed in offboard mode was triggering control_climbrate_mode. This prevented the vehicle from taking off, since it made the vehicle skip the rampup phase of the takeoff
This commit fixes this by handling the case properly
- updating the global position validity should happen regardless of
being in manual position control mode with only optical flow
- condition_global_position_valid needs to be accurate to adjudicate
main state changes (eg going into AUTO MISSION)
- split out switches from manual_control_setpoint into new message manual_control_switches
- manual_control_switches published at minimal rate (~ 1 Hz) or immediately on change
- simple switch debounce in rc_update (2 consecutive identical decodes required)
- manual_control_switches logged at full rate rather than sampled at (5-10% of messages logged)
- manual_control_setpoint publish at minimal rate unless changing
- commander handle landing gear switch for manual modes
- processing of mode_slot and mode_switch is now split so we only do one or the other (not both)
- a future step will be to finally drop mode_switch and accompanying switches entirely

- re-evaluating mode switches on altitude or position validity change can create confusing when also relying on mode changes via mavlink
- limiting this logic to only apply when disarmed solves the original problem (respecting initial switch position) without introducing potential problems mid-flight
- fixes https://github.com/PX4/PX4-Autopilot/issues/16235
- ekf2 can now run in multi-instance mode (currently up to 9 instances)
- in multi mode all estimates are published to alternate topics (eg estimator_attitude instead of vehicle_attitude)
- new ekf2 selector runs in multi-instance mode to monitor and compare all instances, selecting a primary (eg N x estimator_attitude => vehicle_attitude)
- sensors module accel & gyro inconsistency checks are now relative to the mean of all instances, rather than the current primary (when active ekf2 selector is responsible for choosing primary accel & gyro)
- existing consumers of estimator_status must check estimator_selector_status to select current primary instance status
- ekf2 single instance mode is still fully supported and the default
