22ee837e - [flang][NFC] do not copy fields in fir::RecordType::getTypeList (#145530)

[flang][NFC] do not copy fields in fir::RecordType::getTypeList (#145530) For historical reason, `fir::RecordType::getTypeList` was returning an std::vector, causing the entire field list to be copied when called. It is called a lot indirectly in all type helpers, which themselves are called a lot in derived type heavy code like WRF. The `fir::hasDynamicType` helper is also called a lot, and it can just check for length parameters to avoid looping on all derived type components in most cases.
