LibGUI: Add Widget::repaint() to force an immediate repaint
In most situations, Widget::update() is preferable, since that allows us
to coalesce repaints and avoid redundant work, reducing system load.
However, there are some cases where you really want a paint to happen
right away, to make sure that the user has a chance to see a short-lived
visual state.
