Description Of Change

#15133: The latest TS build errors on InferAttributes with a Type instantiation is excessively deep and possibly infinite. error. Thankfully the fix is easy: Exclude keys inherited from Model before checking its values to reduce the type depth. Should improve perfs too.

No new test needed, but this wasn't caught by our CI yet. Will be once we add TypeScript 4.9

This should also get us ready for TS 4.9, I fixed all new typing issues
