Remove Pointer Tracking in WM: Disable TaskTapPointerEventListener

As part of the effort to remove input code from WM, add a flag to
disable TaskTapPointerEventListener in WM.

Its responsibilities are already handled by other means:
- Taps outside focused tasks are reported to WM directly by
  InputDispatcher using onPointerDownOutsideFocus().
- Freeform window resizing is handled by WM Shell in
  DragResizeInputListener.

Since its behavior is obsolete, remove it safely with a flag.
