This removes the `attr` matcher and adds a `meta` matcher. The previous `attr` matcher is now ambiguous because it doesn't disambiguate whether it means inner attribute or outer attribute. The new behavior can still be achieved by taking an argument of the form `#[$foo:meta]` (the brackets are part of the macro pattern). Closes #13067
