83193b378d Fix retrying failed event persistence (#20148)
If we failed to persist an event and then retried, this would fail due
to a conflict error trying to reinsert the state groups that we are
persisting.

This blocks all new events being persisted in the room until the
instance is restarted (which clears entries from the table matching the
instance name). This is because we always mark the [latest persisted
state group in the room as being
persisted](https://github.com/element-hq/synapse/blob/781d08df263e640d85ca5c8b5ff514433e019c6f/synapse/storage/databases/state/deletion.py#L242-L243).

Also add an `inserted_ts` field which we use to detect stale entries,
e.g. from instances that have been taken offline permanently. These
aren't a problem beyond blocking deletion of the associated state groups

Introduced in https://github.com/element-hq/synapse/pull/18107
