if VisualTarget is not ItemsControl then VisualTargetItem = VisualTarget. Allows HighlightAdorner to be used in IDropTarget.Drag.
allow adorners on non-ItemControls (e.g. a label representing a collection, who's collection is rendered with it.)

Consider a listbox bound to a collection representing groups of items. You want to drag into the list or in an item. The item implements IDropTarget, and you need it to show HighlightAdorner - but that only works on a valid VisualTargetItem which is only set on ItemsControls. Added code to fallback setting VisualTargetItem = VisualTarget, and checking for target adorner on any target UIElement.
