tdf#137363 DOCX filter: don't loose <w:ilvl w:val="..."> of paragraph styles

This adds doc model, UNO API and DOCX import/export for this feature.
The rest is not yet implemented (i.e. no layout, UI, etc.)

An alternative would be to grab-bag the list level of paragraph styles,
putting it to the doc model directly has the benefit that this is a step
in the right direction.
