Instrument `_check_sigs_and_hash_and_fetch` to trace time spent in child concurrent calls (#13588)
Instrument `_check_sigs_and_hash_and_fetch` to trace time spent in child concurrent calls because I've see `_check_sigs_and_hash_and_fetch` take [10.41s to process 100 events](https://github.com/matrix-org/synapse/issues/13587)

Fix https://github.com/matrix-org/synapse/issues/13587

Part of https://github.com/matrix-org/synapse/issues/13356
