WindowServer: Introduce the window roll-up feature

Browse source 
The roll-up feature allows the user to set the window content to be
hidden, while retaining the window title bar visibility.
While in roll-up mode, the window height size is not changeable.
However, tiling the window or maximizing (as well as unmaximize) it will
instruct exiting the roll-up mode.
