        [V8] Teach ScheduledAction::execute about isolated worlds
        https://bugs.webkit.org/show_bug.cgi?id=27703

        We now save a handle to the original context.  We use that handle to
        call the timeout in the right context / world.

        Tests: http/tests/security/isolatedWorld/window-setTimeout-function.html
