Input: update input_mt_report_pointer_emulation to support hovering
For devices that are incapable of reporting per-contact distance and can
only report ABS_DISTANCE, just distance is not enough for upper layers of
OS to determine whether contact is leaving the area or if it is continuing
hovering, we need BTN_TOOL_FINGER for that:
Contact State
Inactive Hovering Active
(far away) (inside hover area) (touching surface)
BTN_TOUCH 0 0 1
BTN_TOOL_FINGER 0 1 1
ABS_DISTANCE N/A 1 0
