fix hover events consume issue

View#onHoverEvent() would always consume hover events over the view
if an application window has the clickable view/widget on it.
That's happened even if accessibility/talkback is disabled.
So those events will not dispatch to activity#onGenericMotionEvent().

The onHoverEvent method should return a real consumed state.
