Repro -- ListControlFormatRefreshes.cs

ListBox and ComboBox each inherit from ListControl.  When their FormatInfo,
FormatString, FormattingEnabled properties are changed the display doesn't
update.  On forced repaint the changes are seen.

Repro attached.  On changing any of the three properties the display should
immediately update.  Currently on Mono the change is only seen when one forces
repaint e.g. by clicking on an item.

On each change:
* ListBox -- All (visible) items should refresh.
* ComboBox DropDownList mode --
If there's an item in the 'textbox' (ie selection made previously), it should
(The items in the drop-down are always refreshed at open).
* ComboBox DropDown mode --
If there's an item in the 'textbox' (ie selection made previously and no typing
subsequently), it should refresh.
* ComboBox Simple mode -- All (visible) items should refresh.
