1. Add object_fast_operator file as the middle layer. 2. move store/load method from fast_runtime_stubs to object_fast_operator 3. delete fast_runtime_stubs fastGet/SetProperty methods, and move them to object_fast_operator Issues: https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I6AZSI Signed-off-by: weng-xi <wengxi1@huawei.com> Change-Id: If4aebd3a0723eda641e214d81838caebf193aac2
