Fix #552 Impossible to stop helicopter rotor if it has a driver

[FileEX]

Fixed #552

This PR add two new functions

bool setVehicleRotorState(vehicle, bool state [, bool stopRotor = true ])
bool getVehicleRotorState(vehicle)

This function works in a similar way to setVehicleEngineState.

By specifying state to false, the rotor will not be processed, i.e. it will not change its speed and the helicopter/plane cannot be controlled.

The stopRotor parameter specifies whether the rotor is to be stopped (SetHeliRotorSpeed ​​to 0). If we specify false, the rotor will not change its speed, but will not be stopped, it will rotate at the same speed all the time.

Of course, instead of adding new functions, we could use setVehicleEngineState, but for backward compatibility reasons it is better not to do this and simply add these two new functions to avoid possible problems with older scripts.

This function also allows to achieve the effect that the rotor rotates even without a driver.

Will it work with planes, or only helicopters?

This PR only applies to helicopters. Does the same bug apply to planes?

Does the same bug apply to planes?

Yep, same. At the moment, rotor can be stopped only in preRender.

Im ask because PR #2548 add combined method for set/get heli/plane rotor speed.
It would be good if the rotor-state methods was universal.

What may be broken?

As far as I know, the MTA team strongly attaches importance to backward compatibility.

In this case, various scripts using setVehicleEngineState could cause the helicopter's rotor to stop, and while this is perfectly desirable behavior for us, it may be undesirable for others. So I personally think it's safer and better to just add these simple functions

I took this into account and introduced setVehicleRotorState & getVehicleRotorState which is for both helicopters and planes
