worker.App: onOrientationChange() => limit the scope to affected windows

[tobiu]

@Dinkh: adding an orientationchange notification for apps is a good idea in general.

however, the multi-window aspect probably should get honored.

tricky one: we could argue that the event can only happen on mobile where all windows are affected anyway.

edge-case: desktop, where you debug a specific window in the mobile view and switch the orientation there. in this case, other windows are not affected.

low prio.

@tobiu In fact this will only affect Desktop. And for desktop it seems more likely to use responsive settings than orientationchange.

For Tablets and Phone this should not matter, as you cannot have resizable windows.

I would argue, that this issue should be closed.
