6443657d - [clang][AST] Teach `CXXTypeidExpr::isMostDerived` to use `isEffectivelyFinal` (#196544)

[clang][AST] Teach `CXXTypeidExpr::isMostDerived` to use `isEffectivelyFinal` (#196544) Resolves #196476. When a class is marked final, typeid on references to that type can be resolved at compile time since the most-derived type is statically known.
