The unstable const_default_impls (#87864) already include empty Vec<T> and String. Now we extend that concept to Box<[T]> and Box<str> as well.

This obviates a hack in rustc_ast's P::<[T]>::new.

Thank you for submitting a new PR for the library teams! If this PR contains a stabilization of a library feature that has not already completed FCP in its tracking issue, introduces new or changes existing unstable library APIs, or changes our public documentation in ways that create new stability guarantees then please comment with r? rust-lang/libs-api @rustbot label +T-libs-api to request review from a libs-api team reviewer. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary
