Don't defer platform backingstore creation if we already have a platform window
The creation was made lazy in 18f415e46d592f, for those platforms (macOS) that
need a platform window to successfully create a platform backingstore. But we
don't need to delay creation if we actually have a platform window at the time
of constructing the QBackingStore.
