Fushan Wen 1719c9cc07 Enable using stylus to switch focus and operate on the decoration
Add `tabletToolEvent()` to DecorationEventFilter class so it can handle
tablet events.

Add `tabletToolEvent()` to MoveResizeFilter class to avoid incorrect
titlebar highlight after a window is resized by using a stylus.

Add `tabletToolEvent()` to WindowActionInputFilter class so window focus
can be changed by clicking on the window content area when using a stylus.

Add `update()` to `TabletInputRedirection::tabletToolEvent()` to enable
switching window focus by using a stylus.
