sw: make ODT export of paragraph auto-styles deterministic
If a complex enough document is loaded into Writer and saved as ODT, then the content.xml's automatic paragraph styles (P<num>) are re-ordered on each save, which leads to unnecessary noise. The actual random order is created during import by the time we convert direct formatting (e.g. from HTML import) to autostyles, as StylePoolImpl::maRoot stores autostyles in a map that orders autostyle parents based on their pointer address. This has benefits like automatic ordering of item sets and fast comparison, so don't change that, but extend the svl API to also track the name of those parents. This way by the time StylePool::createIterator() would iterate over those autostyles, it can order the parents by their name, so two import->export runs will result in the same autostyle ordering. (This appears to be the only indeterminism in content.xml for a test HTML input, while meta.xml and settings.xml still changes all the time.)
