Moved the **WebMessagePort** class to **@ohos.web.webview.d.ts** and added error throwing.

**Change Impact**

If your application is developed based on earlier versions, note that the **d.ts** file storage location and the name of the module to be imported are changed. In addition, be mindful of the error codes now that the APIs in the class support error code processing.

  ```ts
  postMessageEvent(message: WebMessage): void;
  onMessageEvent(callback: (result: WebMessage) => void): void;
  ```

**Adaptation Guide**

Instead of importing APIs from the original **WebMessagePort** class, import APIs from **@ohos.web.webview** as follows:

  ```ts
  import web_webview from '@ohos.web.webview';
  ```

## cl.web.7 Moving of the HitTestValue Class

Moved the **HitTestValue** class to **@ohos.web.webview.d.ts**; changed **HitTestValue** from a class to an API; changed the **getType** and **getExtra** from APIs to attributes.
