Fixed some types removed useless header applied clang format fixed compile tests fixed clang tidy, and closer to logic before this MR Removed hardcoded refids unless there is a returned value we don't use static RefIds can use == between RefId and hardcoded string Fix clang format Fixed a few instances where std::string was used, when only const std::string& was needed removed unused variable
