LayoutSaver: Support the user's factory func doing remapping

Browse Source 
While restoring a layout, we expect all widgets to exist already,
but we allow the user to create them delayed, by providing
us a factory function.

What we're supporting in this commit is the ability of the user's
factory function returning a dock widget with an ID different
than the one that was requested. We then save that mapping so the
rest of the layout restore works with the new ID.
