Erik Johnston 55b0aa847a Fix GHSA-3h7q-rfh9-xm4v 
Weakness in auth chain indexing allows DoS from remote room members
through disk fill and high CPU usage.

A remote Matrix user with malicious intent, sharing a room with Synapse
instances before 1.104.1, can dispatch specially crafted events to
exploit a weakness in how the auth chain cover index is calculated. This
can induce high CPU consumption and accumulate excessive data in the
database of such instances, resulting in a denial of service.

Servers in private federations, or those that do not federate, are not
affected.
