The document had overlapping text on load since commit
05425f73bf (sw floatable: teach the RTF
import about SwFormatFlySplit, 2023-04-21).
Interestingly the DOCX equivalent was fine, there the inline table is
shifted down, below the floating table, so the overlap doesn't happen.
Fix the problem by moving the AddVerticalFrameOffsets=true code from the
DOCX filter to the shared dmapper, because RTF needs the same.
See commit 50223ea6e2 (tdf#98987 sw: add
AddVerticalFrameOffsets compat mode, 2016-03-31) for more details about
this compat flag. It was already enabled for DOC, too.
