tdf#95213 DOCX import: don't reuse list label styles

We used to optimize the creation of these styles, so in case two list
label had the same character properties, then we could avoid creating
two styles for those.

This isn't correct though: it means if the style is changed later by the
user, then unexpected other places in the document will change as well.
Do what the binary DOC filter does: create one character style for each
level of a numbering separately.
