lok: Introduce a "TakeOwnership" filter option for saveAs().

It is consumed by the saveAs() itself, and when provided, the document
identity changes to the provided pUrl - meaning that '.uno:ModifiedStatus' is
triggered as with the "Save As..." in the UI.

This mode must not be used when saving to PNG or PDF.
