Kegan DougalandEric Eastwood 54bfa1a01b MSC4242: State DAGs (storage) (#19718)
Split out from https://github.com/element-hq/synapse/pull/19425

Add storage functions needed for federation support for MSC4242:
- `get_missing_events_state_dag`: will be used to satisfy
`/get_missing_events` requests.
 - `get_state_dag`: will be used to satisfy `/send_join` requests.


Part of a series of 5x PRs to land the federation part of MSC4242
(storage, fedclient, serving, inbound-joins, inbound-pulls).
