This event is just used to notify the caller when the tool's no longer in
proximity. When an event like this occurs, everything from evdev up until the
next EV_SYN event is discarded along with any events that occured since the last
EV_SYN event. This also silences any tool update events where the tool type is
changed to LIBINPUT_TOOL_NONE, so we don't end up filling the tool list with a
bunch of tools that aren't actually tools.
