zoltanvb e5e7e66199
Add sensor function placeholders for all joypad drivers. (#16812) 
In some cases, set_sensor_state and get_sensor_input are
more related to the joypad driver, e.g. in desktop platforms
where sensors are associated rather with the joypad.

If input driver supports the sensors, it is still preferred.
Placeholder inserted for all input drivers, no functionality
added yet.
