sw pad-to-3 numbering: add doc model, UNO API and layout

This is similar to the existing padded numbering, but that one padded to
2.  Another difference is pad-to-2 has more file format support:
pad-to-3 is not supported in DOC and RTF.

(cherry picked from commit f4dd9ecdc21696b360dedf7fefa371c8858c1830)
