Move drag event to InputDispatcher (3/n)
This CL re-implements the drag hover detecting in InputDispatcher,
moving it away from DragState.
Currently, any window or windowless surface could receive drag event if
it is visible and touch-deliverable. But it's hard to tell if a surface
could receive this drag event in WM side because we didn't know the
final touch region of the surface that could be cropped by others.
The new expected behaviors are:
- DragAndDropController will transfer touch to drag window when perform
drag, and InputDispatcher will store drag window when transfer
touch focus.
- InputDispatcher will start detecting drag hover window by pointer.
- Send drag exit if drag pointer leave the window.
- Send drag event to the target window during moving.
