tdf#76260 DOCX import: fix slow footnote import

by parsing footnotes.xml only once instead
of parsing again and again for every footnotes.
This was a serious performance problem for
documents with hundreds of footnotes, where the
footnote import took minutes instead of seconds.

Note: switch off CHECK_NOTMERGED in a debug build
to measure realistic speed-up, e.g. with the
reported document: 2 min 36 sec -> 22 sec, and
not 1 min 40 sec, as with CHECK_NOTMERGED.

Revert commit 60dbe21f59a45889c433727d0862c9a4274d94d2
("tdf#88126: sw_ooxmlexport15: Add unittest"), because
it was a fragile table layout test, worked only by accident.
