Fix `TyKind::is_simple_path`. PR #98758 introduced code to avoid redundant assertions in derived code like this: ``` let _: ::core::clone::AssertParamIsClone<u32>; let _: ::core::clone::AssertParamIsClone<u32>; ``` But the predicate `is_simple_path` introduced as part of this failed to account for generic arguments. Therefore the deriving code erroneously considers types like `Option<bool>` and `Option<f32>` to be the same. This commit fixes `is_simple_path`. Fixes #103157.
