yingguofeng@huawei.com 09aaafead4 Setter/Getter Optimization
1、std::array copy construction has high performance overhead,
2、Class is transferred to dictionary after adding getter and setter, resulting in IC failure

https://gitee.com/openharmony/ark_js_runtime/issues/I55EFB?from=project-issue

500000 getter: 170ms > 105ms
