 Provides a fully configured WKWebViewConfiguration which will be overridden
 with any related settings you add to config.xml (e.g., `PreferredContentMode`).
 This is useful for more complex configuration, including `websiteDataStore`.

 ## Example usage

 ```swift
 extension CDVViewController: CDVWebViewEngineConfigurationDelegate {
     public func configuration() -> WKWebViewConfiguration {
         // return your config here
     }
 }
 ```
