[PyTorch] Avoid refcount bump in UnionType::canHoldType (#66693) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/66693 Passing a `TypePtr` by value causes an unnececssary refcount bump. We don't need to take ownership, so `const Type&` is all we need. I considered providing a compatibility shim that takes `const TypePtr&`, but doing so is dangerous because a copy is required to convert from a more specific pointer like `NoneTypePtr`. ghstack-source-id: 140737081 Test Plan: CI Reviewed By: suo Differential Revision: D31691869 fbshipit-source-id: f766ce3234a28771c2a9ca4c284eb3f96993a3d0
