Marco Hauswirth 4bc5875400 ekf2: implement multi-instance AGP fusion
- Refactor aux_global_position into manager + per-source AgpSource class
- Support up to 4 independent AGP sources simultaneously
- Dynamic parameter lookup without boilerplate switch statements
- Per-source state tracking and fusion logic
- Update simulator to use new AuxGlobalPosition message

Daniel Agar e3309b9f87 ekf2: rng don't allow bad measurement in bad_acc_vertical (#25636)
- if bad vertical acceleration is detected there's an emergency case
   where rejected range finder observations are allowed to be used, but
   this still can't happen if the sample itself is known to be bag

c9206d6bd1 EKF2: gnss reset improvements (#25297)
* ekf2: allow manual position reset when horizontal aiding is active

This allows the pilot to override position esitmates manually

* mavlink sim: add support of failure gps struck

* mavlink sim: add GNSS failure "wrong" type

* ekf2-gnss: add reset mode

This allows the user to choose whether the position should immediately
be reset to GNSS on fusion timeout or if the EKF can continue with
velocity dead-reckoning.

* ekf2: fix unit test changes due to GNSS start logic

Especially because the EKF doesn't need to reset the states if the test
ratio is already passing

* rename mode enum

* reset to gps lat lon on init

* remove obsolete reset-condition (handled in #25223)

* WIP try to upgrade compiler externally

bresch aeb182a8ed ekf2: rename resetAltitudeTo to initialiseAltitudeTo

bresch 1a0f97ebbd ekf2-fake pos: add valid fake position fusion
This is similar to fake pos but is only used when the ekf has an
external information telling it that the vehicle is not changing
position. This information can then be used to keep a valid local
position even when the vehicle isn't exactly at rest.
