ref_store: implement `refs_peel_ref()` generically

We're about to stop storing packed refs in a `ref_cache`. That means
that the only way we have left to optimize `peel_ref()` is by checking
whether the reference being peeled is the one currently being iterated
over (in `current_ref_iter`), and if so, using `ref_iterator_peel()`.
But this can be done generically; it doesn't have to be implemented
per-backend.

So implement `refs_peel_ref()` in `refs.c` and remove the `peel_ref()`
method from the refs API.

This removes the last callers of a couple of functions, so delete
them. More cleanup to come...
