tdf#125909 tdf#141298 sw: show (Hidden) Track Changes infobar

instead of enabling Track Changes toolbar automatically,
when there are hidden track changes data or settings in
the document, i.e. Track Changes toolbar and Show Changes
are disabled, but

– the document contains (not visible) recorded changes, or

– Record Track Changes is enabled (which will result hidden
  recording, e.g. unintended publishing of the deletions of
  the document); or

– both of them.

Messages of the infobar show these cases.

Button of the Track Changes infobar allows to show/hide the
Track Changes toolbar. Hiding the Track Changes toolbar with
button of the Track Changes infobar closes the infobar, too.

Regression from commit afbbfb3b55beb937555a972d9edbb47ede91001a
"tdf#83958: sw: enable Track Changes toolbar automatically" and
commit 1989201c56c03b1ef13a282cfd09af69620040ea
"tdf#138870 sw: fix Track Changes toolbar reappearing".
