bug-report
### Describe the bug
Ok - so this is a real one. I thought I just messed up som… e branches / versions etc last time I caught this, but it happened again.
https://github.com/PX4/PX4-Autopilot/issues/21358#issuecomment-1696323289
Title describes it. Leads to runaway.
Sets IDLE position setpoint type instead of takeoff.
My guess is some bug in navigator on that command, not setting the right item for some reason .. and then secondary issue on fixedwing position controller that holds the last throttle command (which was initialized to cruise throttle in position mode) -- but need to investigate further.
### To Reproduce
I haven't been able to reliably reproduce yet. This is only second time I've seen it. But order of operations:
1. `make px4_sitl gazebo-classic_plane`
2. make a mission with a takeoff
3. slide for takeoff in QGC
4. let it finish the mission
5. dont delete the mission if it asks you to
6. kill the sim
7. `make px4_sitl gazebo-classic_plane`
8. dont delete the mission if it asks you to
9. slide for takeoff in QGC
10. plane will keep cruise throttle but set IDLE mode position setpoint type
### Expected behavior
Should set takeoff item, and takeoff properly.

PX4:main ← PX4:pr-fw-pos-c-airspeed-takeoff-main
opened 01:45PM - 11 May 23 UTC
### Solved Problem
Airspeed setpoint at beginning of FW takeoff is set to AIRSP… D_TRIM, and then slowly ramped down to TKO_AIRSPD.
Fixes https://github.com/PX4/PX4-Autopilot/issues/21567 (beside other PRs)
### Solution
Add argument in_takeoff_situation to adapt_airspeed_setpoint(), and do not run airspeed setpoint slew rate limiting then. Also disable some other logic, and only keep the load factor to airspeed setpoint logic while in takeoff.
### Test coverage
SITL tested.

After this PR:
Now the airspeed setpoint is at the set 12m/s when the takeoff starts, and not at the TRIM airspeed (15).
