This change fixes GC-leak caused by following mutual dependency: - SVGDecodedImageData owns JS::Handle for Page. - SVGDecodedImageData is owned by visited objects. by making everything inherited from HTML::DecodedImageData and ListOfAvailableImages to be GC-allocated. Generally, if visited object has a handle, very likely we leak everything visited from object in a handle.
