This gets the necessary data to the issuelist for it to support a clickable commit status icon which pops up the full list of commit statuses related to the commit. It accomplishes this without any additional queries or fetching as the existing codepath was already doing the necessary work but only returning the "last" status. All methods were wrapped to call the least-filtered version of each function in order to maximize code reuse.
Note that I originally left `getLastCommitStatus()` in `pull.go` which called to the new function, but `make lint` complained that it was unused, so I removed it. I would have preferred to keep it, but alas.
The only thing I'd still like to do here is force these popups to happen to the right by default instead of the left. I see that the only other place this is popping up right is on view_list.tmpl, but I can't figure out how/why right now.
Fixes #18810
