tdf#108496: DOCX: redesign of override in lists

List level overrides are not just about numbering,
it is about numbering restart. Thus some changes to DOCX
import/export were added.

Improved support for several lists referring the same
abstract list, especially in situation when one list
have overrides.

In addition some export cleanup is made: less unnecessary
list duplications, less level overrides when no properties
were changed.
