[Development] Qt Quick Controls Dialogs -- enabled state of the standard buttons (API choices)

[Filippo Cucchetto]

I totally agree with the solution proposed by mitch c. With the only
exception that i would add a DialogButtonGroup qml element into which put
the buttons. This allows us to add functions and logic without clutturing
the Dialog component. Furthermore it matches the widget implementation.
