WindowServer+LibGUI: Pass window icons as shared buffers rather than paths.

Browse source 
Now that we support more than 2 clients per shared buffer, we can use them
for window icons. I didn't do that previously since it would have made the
Taskbar process unable to access the icons.

This opens up some nice possibilities for programmatically generated icons.
