backends/native: Deprecate LIBINPUT_EVENT_POINTER_AXIS

Browse Source 
Ignore deprecated LIBINPUT_EVENT_POINTER_AXIS events and handle
LIBINPUT_EVENT_POINTER_SCROLL_WHEEL,
LIBINPUT_EVENT_POINTER_SCROLL_FINGER and
LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS instead.

The scroll source is now encoded in the event type making
libinput_event_pointer_get_axis_source and translate_scroll_source
redundant.
