Add Overlay attached properties and signals

[ChangeLog][Controls][ApplicationWindow] Deprecated the overlay grouped
property in favor of the newly introduced Overlay attached properties.

[ChangeLog][Controls][Overlay] Introduced Overlay attached properties
and signals that supersede the overlay grouped property in Application
Window. The Overlay attached type allows providing background dimming
for popups without requiring an ApplicationWindow instance.
