wheel: accumulate scroll when direction changes

Most mice with high-resolution support have a mechanism in place to
adjust the wheel to a detent. When scrolling, it is possible to stop
between two detents and this mechanism could generate a small amount of
scroll in the oposite direction.

Track the scroll direction in the wheel state machine and reset it when
the direction changes to avoid this issue.
