Add shitty setVehicleModelExhaustPosition/getVehicleModelExhaustPosition

On long term, this function should be deprecated and merged with a new setVehicleModelComponentPosition (sets component position per model id).
Alternatively, an even better solution would be to make this function vehicle-specific rather than model-specific
