This applies the changes introduced in `Project.public_or_visible_to_user`
to the snippets finder only.

We know that for `SnippetsFinder`, this change improves SQL timing from
5/23/25s to 0.7/2/4s (mean/p95/p99). At the same time, the scope was too
broad, (negatively) affecting SQL timings in various other places:

https://gitlab.com/gitlab-com/infrastructure/issues/3772

With this commit, the snippets dashboard stays usuable as we generally
don't run into statement timeouts. In contrast to the earlier change in
!17088, the scope of the change is limited to `SnippetsFinder` only,
thus not affecting other places.

These changes were introduced in MR
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/17088. In
https://gitlab.com/gitlab-com/infrastructure/issues/3772 we discovered
these changes lead to a pretty drastic increase in SQL response timings.

We'll revert these changes so we can work on a better solution in the
mean time without GitLab.com (or other installations) experiecing
reduced performance in the mean time.

In some situations (listing labels for epics) we want to
list only group ancestor labels, this is already supported
in LabelsFinder we just need to enable additional parameters.

Also `set_issuables_index` method now loads project labels only if
@project is set (which is not used for epic group labels).
