tdf#141964 writerfilter CN: only one style per outline level

This really surprised me. On outline numbering, only one style
can use the level of a numbering rule. Any other style that
has it defined is ignored. First come first served.
[All based on experimentation, no documentation found.]

There are two ways the style can be attached.
The highest priority is if the numbering style itself has
a paragraph style defined (which obviously is exclusive).
The second way is just to assign a list level along
with a numbering rule in the para style.
Surprisingly, this too creates an exclusive lock on the level.

These are some existing unit tests that triggered.
I forget which ones are important or valuable,
but none of the contents were affected,
only the UI use of the style didn't apply numbering in Word:

Example1 -ooxmlexport6 fdo74605.docx RT
pStyle not written out for numbering.
List-number-2 gets ilvl0 before List-number-1,
and loses pStyle for absLevel 1
[NOT REALLY A PROBLEM.
That is also how Word sees it. These aren't chapter numbering,
so the pStyle settings just get dropped.]
Example 2 - ooxmlexport7 fdo76979.docx RT:
Bullet gets the numbering, but not Bullet2
Example 3 - ooxmlexport11 tdf101122_noFillForCustomShape.odt RT:
Heading 9 gets the numbering, but not Heading 10
[Typical LO-originating document.]
Example 4 - ooxmlexport13 tdf95848.docx RT:
Heading 1, so not Heading 2
Example 5 - ooxmlexport14 tdf136929_framesOfParagraph.odt RT:
OOoNum123Start, so not the others (who inherit from start anyway)
