refs: create and use `ref_update_expects_existing_old_ref()`
The files and reftable backend, need to check if a ref must exist, so that the required validation can be done. A ref must exist only when the `old_oid` value of the update has been explicitly set and it is not the `null_oid` value. Since we also support symrefs now, we need to ensure that even when `old_target` is set a ref must exist. While this was missed when we added symref support in transactions, there are no active users of this path. As we introduce the 'symref-verify' command in the upcoming commits, it is important to fix this. So let's export this to a function called `ref_update_expects_existing_old_ref()` and expose it internally via 'refs-internal.h'.
