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)

-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

Silvan Fuhrer ebdc29bc5f Airspeed Selector: enable airspeed_validated in control modules (#12887)
* FW attitude controller, FW position controller and VTOL attitude controller subscribe to airspeed_validated topic
* add possibility to switch off the airspeed valid checks
* remove airspeed valid checks from commander
* clean up of VTOL transition logic
* Airspeed Selector: remove dynamic allocation of airspeed validators (depending on number of connected sensors) but do it statically for the maximum number allowed. Check for number of connected sensors not only during start up, but always when vehicle is disarmed.
* Airspeed Selector: change work queue from lp to att_pos_ctrl as this module is safety-critical
* add airspeed selector to px4_fmu-v2 defaults

Julian Oes 2ac8841f35 vtol/fw/mc: fix VTOL enum shadowing
This changes the enums used for various VTOL states to enum classes
which makes them type-safe and should avoid shadowing.

This change was motivated by a Clang warning about shadowing of the
enum const TRANSITION_TO_FW which was declared twice, once in
vtol_type.h and once in standard.h.

This change only removes the shadowing but presumably these enums could
be cleaned up and consolidated further.

Roman deed462e62 tiltrotor back-transition improvements:
- do not set zero throttle during the entire back-transition because otherwise
we need to make the back-transition really short
- added ramping up of throttle setpoint during backtransition to avoid
step inputs
- back-transition ends after back-transition time and not when motors are fully
rotated updwards. previously the vehicle would enter hover mode at high speed
which was not handled well by the mc position controller
