changelog: move branchinfo to changelogrevision
The function parses the extra dictionary after looking up the
changelogrevision. To avoid duplicated look up, it is better to provide
it as property of changelogrevision instead. Keep the function for a
release cycle as at least the topic extension depends on it.
