This is a rerun of the scripts that created #626, off of the current state of the repository. It is meant to replace both #626 and #645, which have become full of unrelated commits.
To recap, in this PR:
System manifest preference key descriptions updated with official texts where available, except for root descriptions where the official ones are empty
Common preference keys in all manifests as well as in the manifest template updated with official descriptions
Reference description tags removed from updated preference keys
I think that this PR has become too stale to merge at this point. If there's still interest in updating to the official descriptions, I'm happy to generate a new one after the current OS beta period.
