Arpad Müller 76328ada05 Fix unoffload_timeline races with creation (#9525) ...

This PR does two things:

1. Obtain a `TimelineCreateGuard` object in `unoffload_timeline`. This
prevents two unoffload tasks from racing with each other. While they
already obtain locks for `timelines` and `offloaded_timelines`, they
aren't sufficient, as we have already constructed an entire timeline at
that point. We shouldn't ever have two `Timeline` objects in the same
process at the same time.
2. don't allow timeline creations for timelines that have been
offloaded. Obviously they already exist, so we should not allow
creation. the previous logic only looked at the timelines list.
