## Summary Follow-up to #13147, this PR implements the `AstNode` for `Identifier`. This makes it easier to create the `NodeKey` in red knot because it uses a generic method to construct the key from `AnyNodeRef` and is important for definitions that are created only on identifiers instead of `ExprName`. ## Test Plan `cargo test` and `cargo clippy`
