    js: Adapt to new JS_DefinePropertyById() API
    
    Like JS_DefineProperty() could already, JS_DefinePropertyById() is now
    overloaded to take several types as the property value. This allows us to
    pass rooted objects directly in, in order to avoid creating temporary
    JS::Values.
    
    Also, JS_PropertyStub and JS_StrictPropertyStub are not allowed as values
    for getter and setter. I previously thought that passing NULL for the
    getter and setter was different than passing the stubs, but it doesn't
    seem to make a difference after all.
