Alex Waygood d02c9ada5d [ty] Do not carry the generic context of Protocol or Generic in the ClassBase enum (#17989) ... ## Summary It doesn't seem to be necessary for our generics implementation to carry the `GenericContext` in the `ClassBase` variants. Removing it simplifies the code, fixes many TODOs about `Generic` or `Protocol` appearing multiple times in MROs when each should only appear at most once, and allows us to more accurately detect runtime errors that occur due to `Generic` or `Protocol` appearing multiple times in a class's bases. In order to remove the `GenericContext` from the `ClassBase` variant, it turns out to be necessary to emulate `typing._GenericAlias.__mro_entries__`, or we end up with a large number of false-positive `inconsistent-mro` errors. This PR therefore also does that. Lastly, this PR fixes the inferred MROs of PEP-695 generic classes, which implicitly inherit from `Generic` even if they have no explicit bases. ## Test Plan mdtests		2025-05-22 21:37:03 -04:00
