This function combines 'GI.Gio.Objects.MenuAttributeIter.menuAttributeIterNext' with
'GI.Gio.Objects.MenuAttributeIter.menuAttributeIterGetName' and 'GI.Gio.Objects.MenuAttributeIter.menuAttributeIterGetValue'.

First the iterator is advanced to the next (possibly first) attribute.
If that fails, then 'False' is returned and there are no other
effects.

If successful, /@name@/ and /@value@/ are set to the name and value of the
attribute that has just been advanced to.  At this point,
'GI.Gio.Objects.MenuAttributeIter.menuAttributeIterGetName' and 'GI.Gio.Objects.MenuAttributeIter.menuAttributeIterGetValue' will
return the same values again.

The value returned in /@name@/ remains valid for as long as the iterator
remains at the current position.  The value returned in /@value@/ must
be unreffed using 'GI.GLib.Structs.Variant.variantUnref' when it is no longer in use.
