Add Vehicle.IsConsideredDestroyed

Another simple and useful feature.

Maybe just IsDestroyed?

I don’t think IsDestroyed is a appropriate name, because IS_ENTITY_DEAD will always return true if (*(byte*)(CVehicle + 0xD8) & 7) == 3 is true. With memory editing, we can even make exploded vehicles considered not destroyed by the game so peds can enter them.

IS_ENTITY_DEAD will also return true if the entity is vehicle and some kind of sinking flag is set (for vehicles sinking for a short time). That flag will be removed when vehicles are not in water though.

Oh wait, more convincing fact. Changing the value of (byte*)(CVehicle + 0xD8) does not change if the vehicle is rendered scorched, which can be changed with SET_ENTITY_RENDER_SCORCHED. We can fail missions for vehicles destroyed by changing the value since IS_VEHICLE_DRIVEABLE will return false by doing that on the other hand (even if the vehicles looked completely undamaged).
