Rollup merge of #129659 - RalfJung:const-fn-lang-feat, r=fee1-dead
const fn stability checking: also check declared language features Fixes https://github.com/rust-lang/rust/issues/129656 `@oli-obk` I assume it is just an oversight that this didn't use `features().declared()`? Or is there a deep reason that this must only check `declared_lib_features`?
