oox smartart, accent process: fix missing bullets and large para indent

Bulleted paragraphs had a large left indent because we assumed the
bullet levels are inherited from the normal master page styles.

But that's not true, as
<https://support.office.com/en-us/article/add-bullets-to-a-shape-in-a-smartart-graphic-47edc03d-a2f8-4b54-acfd-ca103c515ab4>
points out:

"It is not possible to change the bullet style for text in a SmartArt
graphic."

This explains why the margin and bullet char info is missing from the
file format, and hints that just hardcoding these to the importer is
correct.

The result is less linebreaks in the shape text and the lost bullets are
also fixed.
