topic: handle ambiguous arguments to topic() revset
These arguments can be interpreted as either string or a revset. The decision
is made based on existence of topic with such a name. This matches the behavior
of branch() revset.
The code needs to know all topics that ever existed in the repo, because some
commands report "disappearance" of topics after certain operations, using this
revset (e.g. via stack.stack or repo.revs).
