related tdf#81705 doc export: eliminate duplicating OutlineNumbering
It just looks redundant. And all three formats
handle it very different.
RTF - never writes RES_PARATR_OUTLINELEVEL
or RES_PARATR_NUMRULE in styles,
only via this OutlineNumbering.
DOCX does nothing. That's because there always
seems to be a RES_PARATR_OUTLINELEVEL and
RES_PARATR_NUMRULE.
DOC does BOTH. It writes RES_PARATR_NUMRULE
(and now also writes RES_PARATR_OUTLINELEVEL)
and also writes them via OutlineNumbering.
So OutlineNumbering seems to always have
been partially redundant and now is fully
redundant. Thus it can be treated like DOCX.
