Optimizes Ci::Pipeline#latest_successful_for_refs to load just the
needed branches in two queries. Instead of loading all branches in one
query then filtering the needed branches in memory.

The function `#commits_for()` has been introduced via 156ce433
(checks: Implement infrastructure for bulk diff checks, 2021-07-29) in
order to allow bulk-loading of commits. What this function does is given
a set of new commits and a specific object ID, it will do a graph walk
of these new commits starting from this ID in order to extract only
those commits which have been newly introduced via this object ID.

As it turns out though, the implementation has a bug which causes
combinatorial explosion: if a commit is reachable via multiple commits,
then it will be walked and returned multiple times. This can happen if
there are merge commits, where we'll now repeatedly walk all common
ancestors of both commits. In case these again contain merge commits,
the common ancestors again get walked multiple times. The result is that
commits get walked exponentially many times. For the following graph
with criss-cross merges, this causes us to return 768 commits instead of
the expected 18:

      o---o---o---o---o---o---o---o
     / \ / \ / \ / \ / \ / \ / \ / \
    o   X   X   X   X   X   X   X   o
    \  / \ / \ / \ / \ / \ / \ / \ /
      o---o---o---o---o---o---o---o

Fix the bug by removing seen commit IDs from the hash tracking commits
by their object ID. Furthermore, the pending queue is converted to a set
such that we don't re-add IDs which we have already seen before such
that it doesn't exhibit exponential growth.
