- added: Websocket Module setCustomClientBuilder (#37798)

Summary:
Added code previously added in the following PR: #28659.

The above PR was accidentally scrapped due to the renaming of the master branch on the React Native repo. As advised in this comment: #37770 (comment), I'm opening a new PR with the same code to get this merged into master / main.

Currently, we need to run a local fork of React Native and manually apply these changes ourselves. This then causes additional issues, as it's currently _**impossible**_ to build React Native from source when running on a Windows machine, as evidenced in #37770 and the other linked issues nested inside of this issue.

**Original summary is as follows:**
With `NetworkModule.setCustomClientBuilder` we can customize our OkHttpClient to all requests made by react-native, it's very useful when you do `SSL Pinning` or change some OkHttpClient configuration at all. I've added a similar function to websocket, it allow us do some configurations on Websocket OkHttpClient.

Pull Request resolved: #37798

Test Plan:
**From the original PR:**

You can just set a custom `CustomClientBuilder` on `MainActivity` `onCreate`:

```
import okhttp3.OkHttpClient;
import java.util.concurrent.TimeUnit;
import com.facebook.react.modules.network.CustomClientBuilder;
import com.facebook.react.modules.websocket.WebsocketModule;

public class MainActivity extends ReactFragmentActivity {

    Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        RNBootSplash.init(R.drawable.launch_screen, MainActivity.this);

        WebsocketModule.setCustomClientBuilder(new CustomClientBuilder() {
            Override
            public void apply(OkHttpClient.Builder builder) {
              builder.connectTimeout(0, TimeUnit.MILLISECONDS);
            }
          });
    }

   ...
```
