LibGUI: Dynamically resize editing content rect in IconView

Browse source 
This makes IconView aware of the text width of the
ModelEditingDelegate widget when editing an index and allows us to
resize the content rect as needed.

This also removes the border from the textbox since it could collide
with the icon in ColumnsView. While editing we also skip painting the
inactive selection rect since it would otherwise show when the content
rect gets smaller.
