Silvan 7e4a53f292 VTOL tiltrotor: introduce spin up time with spin up tilt angle
As some tiltrotor systems need a certain tilt angle of their motors in oder to spin up freely,
this commit introduces an additional parameter VT_TILT_SPINUP and sets the motor tilt to
this value if disarmed or within 1s since arming.

The spinup consists of 2 phases:
    1st phase fixed tilt (duration hardcoded to 1s)
    2nd phase transition from spinup tilt to multicopter tilt (hardcoded to 0.5s)

Silvan Fuhrer a26e914ef4 VTOL pusher/tilt support: addressed review comments:
- remove gloabl variable and instead give back forward_thrust from function
 - give back increased vertical thrust from fct thrust_compensation_for_tilt()

Silvan Fuhrer 5ae4ca8ff1 VTOL: Make pusher assist generic to enable also for tiltrotor
-move pusher assist functionality into vtol_type class and adapt it to also
work for tiltrotor VTOLs (pitch rotors down to accelerate forward)
-for tiltrotor: compensate for lost lift due to tilt by increasing the throttle
-enable pusher / tiltassist also in altitude mode

Roman Bapst 90bfdb6f0a VTOL rate control architecture improvements (#10819)
* attitude and rate setpoint message: use 3D array for thrust demand
* FixedWingAttitudeControl: rework airspeed scaling
  * move airspeed and scaling calculation into separate method
  * if vtol in hover and airspeed disabled use minimum airspeed instead of trim airspeed
