SIH Simulator: Add wind (#26467)

* SIH: explicitly use local velocity for all aerodynamic calculations

no functional change

* SIH: add param & vars for wind and apparent vel

no functional change

* SIH: replace all relevant vels with apparent vel

Only places where _v_E is remaining:
 - ecefToNed to calculate _v_N
 - generate_rover_ackermann_dynamics
 - equations_of_motion
 - parameters_updated, init_variables
and _v_N:
 - ecefToNed
 - print_status
 - publish_ground_truth
 - generate_rover_ackermann_dynamics
 - equations_of_motion
 - parameters_updated, init_variables

which are all not relevant for aerodynamics.

* sih: wind review suggestions

* sih wind: switch direction to global wind source direction convention

* SIH: clean up variable declarations

* SIH: rename variables for consistency

* docs: SIH: document new wind parameters

* Release notes: note for SIH wind settings

+## Simulation Configuration
+
+### Wind
+
+SIH supports setting a wind velocity with the PX4 parameters [`SIH_WIND_N`](../advanced_config/parameter_reference.md#SIH_WIND_E) and [`SIH_WIND_E`](../advanced_config/parameter_reference.md#SIH_WIND_E) [m/s]. The parameters can also be changed during flight to simulate changing wind.
+
 ## Display/Visualisation (optional)
 
 The SIH-simulated vehicle can be displayed using [jMAVSim](../sim_jmavsim/index.md) as a visualiser.
