Description

Once #24596 lands, we could run into scenarios where the deadlock cycle contains virtual txns alone and no regular distributed txn (with object locks / advisory locks enabled).

We need to handle the abort path for a virtual transaction. We should have a mechanism to unblock the waiting requests at the object lock manager (as there is no regular txn, all the waiting requests would have been at the OLM itself), but not abort the virtual txn itself (since that corresponds to the host pg session).
