Wesley Wigham 7748694d60 Relate non-augmenting subtypes without resorting to structural comparison (#43624) ...

* Relate non-augmenting array subtypes without resorting to structural comparison

* Fix lint

* Generalize performance enhancement

* Cache results, feed through via getNormalizedType to remove error intermediates

* Use newly freed up object flags to limit member setting, fix crash with those object flags

* Move flags because there is no TypeFlags.Reference 🤦
