* Refactor IntegrationTestApp.
Use a `ListBox` to switch pages instead of a `TabControl`: the `TabControl` didn't adapt well to smaller screen sizes, and the `MainWindow` was getting unwieldy anyway.
* Update tests to use new pager.
Move logic for selecting the page to a base class as we may need to handle scrolling manually on macOS at some point (Appium on macOS doesn't scroll elements into view automatically).
* Add AutomationPeer.IsOffscreen.
This is needed in order for controls to be scrolled into view using WinAppDriver. The default is the same as WPF and the default value is overridden in the same controls as WPF (where present).

Make the untyped ItemContainerGenerator create `ContentPresenter`
containers when the data isn't a control. This is required for correct
binding to `DataContext` in a data template.
