Add use_proximity bit for BTN_TOOL handling.

Touchpads send garbage data between BTN_TOOL_FINGER and BTN_TOUCH. This
leads to cursor movement towards invalid positions (bottom left corner,
usually).

Add a new flag "use_proximity" as a delimiter for BTN_TOUCH handling. If
unset, the actual proximity bits are ignored, no proximity events are sent
and BTN_TOUCH is used for the tool handling.

Example event stream for synaptics:
