iOS: Implement basic QPlatformOffscreenSurface subclass

Browse Source 
Offscreen surface support was added in fb3577039ca8, as the platform
supports FBOs, but we need to return a subclass of QPlatformOffscreenSurface
that returns true for isValid() and a valid surfaceFormat().

Task-number: QTBUG-39759
