Declarative dialog improvements for the non-Window use case

Platforms like Android and EGL don't support multiple top-level
windows, so we have to avoid trying to use widget-based dialogs
(because a widget dialog on top of a scene graph will result in a
second window), allow the QML dialog to be an Item, and decorate it
to look like a window.
