disable 'quit' menu entry when modal dialog waiting response

Traditionally when a modal dialog is active, the quit menu entry of all
LibreOffice toplevel frames, not just those which are themselves modal, is get
disabled.

This has come unstuck because its implemented by dialogs emitting
MouseNotifyEvent::[END]EXECUTEDIALOG on its parent, and SfxFrameWindow_Impl
listening for that event. But if the dialog parent is the toplevel parent of
SfxFrameWindow_Impl then it doesn't get seen by the SfxFrameWindow_Impl child.
