Subject: [PATCH] tdf#107690 Initial support of Mark as Final property of MSO

Don't save modified documents with property _MarkAsFinal=True
silently to avoid to get unintended warning messages in MSO.

Show read-only info bar for documents with custom document
property _MarkAsFinal=True, similar to MSO.

This improves interoperability a lot, because this is a
basic document protection of MSO, recommended on its UI.
