DialogButtonBox: add contentWidth and contentHeight

This is a follow-up to f1f884d3, which mentioned that:

    This can be fixed properly in dev by providing separate contentWidth
    and contentHeight properties that cleanly propagate the content size
    to QML.

[ChangeLog][Controls][DialogButtonBox] Added contentWidth and
contentHeight properties.
