This pr

  • Deletes the unused DiagnosticAttribute struct and variant
  • Comments the AttributeKind enum
  • The match in CheckAttrVisitor is now exhaustive for AttributeKind::Parsed.
  • Moved some checks around after that change

I did not thoroughly check that there's no duplicated logic between this pass and the attribute parsing but I think it's OK.

Thanks @jieyouxu . I think I read the CI error wrong and that's why I added the <> 😆

I'd like to do that actually, I just thought there shouldn't be a bunch of dead code here at this time.
