Companion PR: element-hq/matrix-authentication-service#5550


Currently Synapse and MAS have two independent user lock implementations. This PR makes it so that MAS can push its lock status to Synapse when 'provisioning' the user.
A companion PR will be made to MAS to 1) send this flag and 2) provision users proactively when their lock status changes.

Having the lock status in Synapse is useful for removing users from the user directory
when they are locked.

There is otherwise no authentication requirement to have it in Synapse; the enforcement is done
by MAS at token introspection time.
