1. add env in JSNativePointer deleter 2. delete new NativeObjectInfo 3. delete NapiNativeCallbackInfo, use ark stackinfo instead https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I9IDMS Signed-off-by: wengchangcheng <wengchangcheng@huawei.com> Change-Id: I1acf0e9f26096319ef74ef20e108ac63c9c2c21c
