Clean up starting window to prepare for saved surfaces
- Move all starting window logic to AppWindowContainerController
- Use startingView to hold any kind of contents for startingWindow
- Remove some conflicting code which looks very old and doesn't
apply anymore.
Test: Make sure starting window still works.
