tdf#130857 qt weld: Hide widget marked for deletion

Add a helper method QtBuilder::deleteObject
that takes care of marking no longer needed
objects for deletion and use it in the 3 places
so far calling QObject::deleteLater themselves.

If the object marked for deletion is a widget,
hide it as well, as it could otherwise still
be "in the way".
This was seen wit the edit (QLineEdit) of the editable
combobox in the "File" -> "Properties" dialog,
"General" tab (in a WIP branch for adding support
for that dialog), where the unnecessary edit was
shown on top of the combobox, hiding the combobox
content + dropdown button.
