13c08ab32b Use identity with the permissive instantation to detect nongenric instances and disable variance probing on nongeneric instances (#29981) 
* Use identity with the restrictive instantation to detect nongenric instances and disable variance probing on nongeneric instances

* Generalize to also include interfaces, add test case, still perform argument comparisons for postive comparisons if possible

* Actually accept baselines, lol

* Reduce deep nesting limit just a bit so yargs still builds

* Handle circular identities in isNonGeneric

* Use a simple traversal of the types rather than the restrictive instantiation

* Cache the bits using an existing field to further reduce any time nongeneric check takes

* Revert to using an existing mapper, use permissive > restrictive

* Revert constant change

* And revert the comment, too
