sw fly frames: add Tooltip uno property

This is somewhat similar to commit
1acf8e3cfaf1ef92008e39514a32ace0d036e552 (sw fields: add Title uno
property, 2022-03-24), except that this is for images, and images
already had a Title, which is persisted to ODT.

So add a new Tooltip property which has priority over the tooltip
generated for URLs, in case the tooltip is non-empty. This helps in case
the URL is long / non-readable / confusing and a more helpful
popup text can be provided instead.
