clutter/input-device: Make clutter_input_device_get_actor() public

Browse Source 
Make the clutter_input_device_get_actor() API public and remove
clutter_input_device_get_pointer_actor() in favour of the new function.

This allows also getting the "pointer" actor for a given touch sequence,
not only for real pointer input devices like mice.
