Instead of tracking a fixed deceleration setpoint during the backtransition we added here position feedback,
such that the vehicle comes to a stop latest at the current position setpoint. This reduces the risk of
overshooting the landing point.
If no position feedback/position setpoint is present the old logic still applies.
It further moves the braking controller to the FlightTaskTransition instad of doing it in
the VTOL attitude mode.
* vtol_type: added position feedback to backward transition
* FlgithTaskTransition: refactored backtransition deceleration/pitch setpoint computation
* FlightTaskTransition: minor improvements
* FlightTaskTransition: use .dot() consistently and remove unnecessary comments

- remove VT_TILT_SPINUP and special spin up tilt handling form the VTOL module
- now handle the spoolup in the allocation, directly linked to COM_SPOOLUP_TIME
- leave tilts at disarmed value during spoolup

Instead of hard-coding the tilting duration (from FW to MC tilt),
expose it as a parameter (VT_BT_TILT_DUR). The default is the same
as the hard-coded value previously (1s).
Slower tilting mechanisms need a higher value here, while for smaller
ones a too high value results in unnecessary delays till the motors
are in hover configuration.

This affects how soon after a backtransition the vehicle has the
full hover controller running again. Specifically it reduces the
duration of the ramp down of the motors prior to tilting them.

- remove deprecated actuator_controls[INDEX_FLAPS/SPOILERS/AIRBRAKES]
- use new topic normalized_unsigned_setpoint.msg (with instances flaps_setpoint
and spoilers_setpoint) to pass into control allocation
- remove flaps/spoiler related fields from attitude_setpoint topic
- CA: add possibility to map flaps/spoilers to any control surface
- move flaps/spoiler pitch trimming to CA (previously called DTRIM_FLAPS/SPOILER)
- move manual flaps/spoiler handling from rate to attitude controller
FW Position controller: change how negative switch readings are intepreted
for flaps/spoilers (considered negative as 0).
VTOL: Rework spoiler publishing in hover
- pushlish spoiler_setpoint.msg in the VTOL module if in hover
- also set spoilers to land configuration if in Descend mode
Allocation: add slew rate limit of 0.5 to flaps/spoilers configuration change
Instead of doing the flaps/spoilers slew rate limiting in the FW Position Controller
(which then only is applied in Auto flight), do it consistently over all flight
modes, so also for manual modes.

- remove deprecated actuator_controls[INDEX_LANDING_GEAR]
- remove dead code in mc rate controller that used to prevent it from being retracted
on the ground (anyway had no effect as it only affected the actuator_control[LANDING_GEAR]
which wasn't sent to the control allocation)
- for VTOLs handle deployment/retraction of landing gear in AUTO as a MC (retract if
more than 2m above ground, deploy if WP is a landing WP), plus additionally when transition
flight task is called (ALTITUDE mode and higher)
- for FW in AUTO: add logic in FW Position Controller, depending on waypoint type mainly
- manual landing gear settings always come through (a manual command overrides a previous
auto command, and vice-versa)

Tiltrotor_extra_controls also contains collective thrust beside collective tilt, as passing a 3D
thrust setpoint vector beside the tilt is not feasible.

This failsafe flag is currently used for not allowing to re-transition to FW, as well
as disabling pusher assist in hover. Till now it was only possible to reset it with
a commanded transition to MC, which many ground station interfaces didn't allow
as the system, after a quad-chute, already was in MC mode.
Hereby it is changed to reset when a new transition to FW is triggered (either via
RC switch or MAVLink command). It is the users responsibility to assess the situation
after a quad-chute happened to try to transition to FW again, manually proceed/land
the vehicle in MC, or let it finish the defined behavior after a quad-chute.

* VTOL: differential thrust in FW: adapt params to be generic for all axes
Until now only suppoted on yaw axis. Not to be supported also on Roll and Pitch.
- VT_FW_DIFTHR_EN: make bitmask for all three axes independently. First bit is Yaw,
sucht that existing meaning of VT_FW_DIFTHR_EN doesn't change.
- VT_FW_DIFTHR_SC: rename to VT_FW_DIFTHR_S_Y and add same params for roll (_R) and
pitch (_P).

This is to prevent that that data from non-recent publications of the virtual
attitude setpoints are used in the transition code.
It removes the previous implementation where the update_transition_state()
method was only run when both mc and fw virtual att sp where recent, independetly
of whether both are used or not.

Special case tiltrotor: instead of passing a 3D thrust vector (that would mostly have a x-component in FW, and z in
MC), pass the vector magnitude as z-component, plus the collective tilt. Passing 3D thrust plus tilt is not feasible as they
can't be allocated independently, and with the current controller it's not possible to have collective tilt calculated
by the allocator directly.

[4] is reserved for Flaps, so also having the tilt on it was preventing us from
using flaps on tiltrotors, and other ripple effects.
By using [8] the tilt is separated from all other channels - it requires to increase the size of
actuator_controls by 1 to 9.

In the tiltrotor case, beside an F_z thrust setpoint also a F_x setpoint must be passed
to the allocator as the matrix has non-zero thrust-x effectiveness when tilts are applied.
