route wizards child queue_resize requests to preexisting layout

As an interim measure, until wizards can only be constructed from .ui and then
always contain layout widgets, implement listening for layout widget children
announcing layout change requests and route that to pre-existing original
positioning code. That allows e.g. the mail merge output page in writer to
show/hide the alternative descriptions on selecting letter/email.
