Add Chromium versions for api.FetchEvent.targetClientId (#10705)

This PR adds real values for Chromium (Chrome, Opera, Samsung Internet, WebView Android) for the `targetClientId` member of the `FetchEvent` API, based upon results from the [mdn-bcd-collector](https://mdn-bcd-collector.appspot.com) project (v3.0.2).  Results are manually confirmed for accuracy.
