Touch handler: Fix race condition and rate-limit move events (#35537)

Browse source 
* TouchSequenceInfo is added to store information about a touch sequence.
  For details about TouchSequenceInfo, see the code comments.
The handling_touch_move attribute is added to the TouchHandler, indicating that the script is processing the touch move event.
  When handling_touch_move is set to true, the touch move event does not need to be sent to the script thread.

* move touch state, active_touch_point and handling_touch_move to TouchSequenceInfo form TouchHandler.
remove TouchSequenceInfo end_sequence property, add Finished state mark sequence end.
if preventDefault on touchup, do not prevent Fling.

* Refactor Touchhandler

- Add a newtype wrapper for the TouchSequenceId
- Move more state back into the TouchSequenceState
- Rename TouchAction to TouchMoveAction,
  since it only covers immediate actions now.
  Everything else is handled via state, since
  it needs to wait on the handler.

* Remove wrong todo comment

(move events that are sent to script are just raw  touchpoints,
 no merging needed)
