LibGUI: Improve and simplify IconView item name wrapping

Browse source 
Move the wrapping logic to get_item_rects(). This makes mouse events
able to hit the wrapped labels, and various other little things stop
glitching out as well.

Also, instead of having a per-line width when wrapping icon names,
make the text rect wide enough to fit every line.
