It has only two uses, and both use `matches_codepattern`. So just change it to `assert_matches_codepattern`.
It's small and has a single call site. Also change the second `parse_meta` call to use a simple `match`, like the first `parse_meta` call, instead of a confusing `map_err`+`ok` combination.

rustc's high-level lexer now provides a public interface returning a TokenStream, so we now use that rather than making a Parser and pulling tokens from it one by one. (And in any case the previous approach no longer works, because Parser::token_spacing is no longer public.) See rust-lang/rust#125815 rust-lang/rust#126052 Other rustc changes: ParseSess now provides a dcx() method rather than a public dcx field. There are new NtIdent and NtLifetime TokenKinds, which AIUI won't appear in token streams created by the lexer.
