tdf#77760 sw floattable: add support for footnotes, doc model

The bugdoc had a floating table, but we didn't convert the inline table
to floating because it had a footnote, and having footnotes in fly
frames is not supported in Writer.

One benefit of not having footnotes in fly frames is that once these are
saved to Word shapes, those can't have footnotes, either -- there is
value in limiting the UI to the constructs that can be also saved in
Word formats.

Fix the problem by allowing this for split flys, but not for
flys/headers/footers in general.

This is just the doc model, later steps (layout, etc) still need doing
in follow-up commits.
