@brief Defines the web message API for native ArkWeb. Before invoking an API, you are advised to use ARKWEB_MEMBER_MISSING to check whether the function structure has a corresponding function pointer to avoid crash caused by mismatch between the SDK and the device ROM. Use OH_ArkWeb_GetNativeAPI in the UI thread to obtain the WebMessagePort-related interface cluster.
