Only run App::ui if the application is visible (#7950)

* Closes https://github.com/emilk/egui/issues/5113

If the application is invisible (occluded or minimized), and the user
calls `.request_repaint`, then we should call `App::logic`, but NOT
`App::ui`.

There are still some situations where `App::logic` is not called when it
should be, but at least now we can skip running the UI code when the app
is invisible.
