Make Repository#has_visible_content more efficient
What does this MR do?
Add two more efficient implementations of Repository#has_visible_content?. The gitaly_has_local_branches feature flag toggles between the two.
Are there points in the code the reviewer needs to double check?
Why was this MR needed?
We have learned that this method is called a lot, and that it is slow on repositories with many branches.
