crimson/os/seastore/backref_manager: retrieve live backref extents throught the backref tree

After involving intra-fixed-kv-btree parent-child pointers, we need to keep the
invariant that it's only when extents are not in transactions' read_set that
we can directly query cache with inspecting the transaction
