Fix freeform window can't resize

The WindowState touch region would be cropped by task bounds, but in
free form window mode, we could has some extra space outside the window
content in order to resize window, we should include the resize border
in the touch region.

- Touch region should include the resize border and prevent it to be
  cropped by task bounds if window is freeform.
- Apply show or hide transaction for InputSurface immediately.
