Drop RENDER_OBJECT_TYPE_CASTS() for a lot of RenderObject subclasses

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Chris Dumez]

Drop RENDER_OBJECT_TYPE_CASTS() for RenderObject subclasses that no longer needed it or that required very few changes to do so. This will make sure developers start using is<>() / downcast<>() for those classes.

We should write this:

    RenderObject* parent = renderer->parent();
    return is<RenderFullScreen>(parent) ? downcast<RenderFullScreen>(*parent).placeholder() : nullptr;

I think the two line version is better than the longer version.
