mc_att_control: replace math::min() and additional limit logic with math::constrain() calls (#11658)

- fixes #11666

It turns out that we can fix the unit tests of the lockstep_scheduler
just by checking if `passed_lock` is not `nullptr`.

Without this check, the unit tests segfaulted.

This fixed running `make tests` on Arch Linux where Python 3 is the
default.

VTOL: unset v1.9 roll direction safety check param for builtin airframes

This inversion matches the fixed sign in the commands generated
by the VTOL attitude controller.
This commit, combined with the previous commit, should have no effect.
For safety, it is recommended to check the direction of roll control
surfaces before flight.

* FlightTaskAuto - Explicitly check is _triplet_target is finite to decide if the target has to be updated or not. If the _target is NAN, always try to update it to get a valid setpoint.

https://github.com/PX4/ecl/pull/590 - EKF: Fix innovation in fuseDeclination()

Enhancements:

https://github.com/PX4/ecl/pull/543 - ekf_helper: add more useful methods to interface with the covariances
https://github.com/PX4/ecl/pull/588 - Add unit tests for DataValidator

Note:

https://github.com/PX4/ecl/pull/543  has required a change to how the state variances are accessed .

Since Timeout from onboard controller is something that does not require a lot of modifications there is no sense to having it parametrized.

Since commander handles all telemetry_status the same there is no need to subscribe to multiple instances.

Major changes:
- Prevent  "HIGH LATENCY DATA LINK LOST" message to appear if iridium telemetry is not used.
- Prevent "DATA LINK LOSS" mavlink messages flooding when QGC is open and then closed.
- Changed "DATA LINK REGAINED" condition (use _datalink_last_heartbeat_gcs insthead of _datalink_lost)
