Use out parameter for generated methods returning JSVal (#34087)

* Make generated bindings that return a WebIDL `any` value use out parameters.

Returning raw JSVal values makes it easier to create GC hazards in code
that calls these methods. Accepting a MutableHandle argument instead
ensures that the values are rooted by the caller.
