Update all stream IDs after processing replication rows (#14723)
This creates a new store method, `process_replication_position` that is called after `process_replication_rows`. By moving stream ID advances here this guarantees any relevant cache invalidations will have been applied before the stream is advanced. This avoids race conditions where Python switches between threads mid way through processing the `process_replication_rows` method where stream IDs may be advanced before caches are invalidated due to class resolution ordering. See this comment/issue for further discussion: https://github.com/matrix-org/synapse/issues/14158#issuecomment-1344048703
