tdf#121561: sw: DOCX: add std/stdPr/stdContent around TOC

During export into DOCX from ODT we need to do it
because in this case the TOC title will be recognized
inside MS Word as part of the TOC.

Later we could add support of these keywords in LO import
in order to detect TOC title from DOCX input.

Added unit test for export.
