Kegan Dougal 48e1e737b9 MSC4242: State DAGs (CSAPI) ...

This implements state DAGs, without support for federation.

A general overview:
 - It adds a new room version and new event type.
 - It adds a new field `calculated_auth_event_ids` to internal metadata.
 - It stores the state DAG via new state DAG edges / forward extremities tables.
 - It adds new auth rules as per the MSC.
 - It uses the new `prev_state_events` field instead of `prev_event_ids()` when doing state resolution.
