[NUI] Cache url when we call SetImage + Make way to skip visual creation

Previously, we don't cache Url infomation at cached property map when we use
SetImage API instead of ResourceUrl property.

Now, let we keep this cache information.

And also, add parameter that we dont want to create new visual when we change
this property.
