Many bindings are probably very much broken

So we define Rooted<T> ourselves to be a simple T wrapper, but for some kinds of values on C++, it is a bit more complex than that, going through MaybeWrapped<T> and ultimately storing a DispatchWrapper<T> which has more fields than a simple T.

So what happens with types such as AutoSaveExceptionState which include a RootedObject, which should actually be using the DispatchWrapper<T> wrapper? Doesn't that mean the layout of that struct is wrong?

        pub struct AutoSaveExceptionState {
            pub context: *mut root::JSContext,
            pub wasPropagatingForcedReturn: bool,
            pub wasOverRecursed: bool,
            pub wasThrowing: bool,
            pub exceptionValue: root::JS::RootedValue,
            pub exceptionStack: root::JS::RootedObject,
        }

We should probably not bind anything that involves the C++ Rooted<T> type.
