    [gin] Delete DeprecatedWrappable

    This CL deletes gin::DeprecatedWrappable, and classes and data
    structures related to gin::DeprecatedWrappable. Additionally it removes
    internal fields of JS wrapper objects that were only used by
    gin::DeprecatedWrappable, but are not needed anymore with the new
    gin::Wrappable.
