[Enhancement] Add ability to create Region while navigation to page

[dansiegel]

Summary

If migrating to more of a Region Based architecture it would be beneficial if we could navigate to a Region View and create a ContentPage on the fly as a Region Container loading a specified Region View.

navigationService.NavigateAsync("HomeView?regionName=RootRegion");

Additional Consideration

When navigating it would be beneficial to be able to set the Title and IconSource at the same time.
