vcl: move OutputDevice::ImplDrawFrameDev() to Window

I have moved ImplDrawFrameDev() from OutputDevice to Window, because it
deals with frames which is clearly the responsibility of the Window class,
not the OutputDevice class which shouldn't really care about it at all.

I've also renamed it to drawFrameDev() as it's a private function.
