This introduces payload to the ServiceResponse with
the merge ref HEAD commit data

This couples the code that transitions the `MergeRequest#merge_status`
and refs/merge-requests/:iid/merge ref update.

In general, instead of directly telling `MergeToRefService` to update
the merge ref, we should rely on `MergeabilityCheckService` to keep
both the merge status and merge ref synced. Now, if the merge_status is
`can_be_merged` it means the merge-ref is also updated to the latest.

We've also updated the logic to be more systematic and less user-based.

Add hover and focus to "Attach a file"

Closes #61339

See merge request gitlab-org/gitlab-ce!28682

Adds migrations to reset the merge_status of opened,
mergeable MRs. That's required by
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28513
so we're able to sync the status update along merge-ref,
without leaving MRs with a stale merge-ref.
