Re: SecurityException caused by ConnectivityManager.registerDefaultNetworkCallback

This issue is a continuation of [9002](https://github.com/google/ExoPlayer/issues/9002). We are still getting the original crash posted in the issue, because the solution shipped is modification to `Requirements.isInternetConnectivityValidated` which is not in the [original stack trace](https://github.com/google/ExoPlayer/issues/9002#issue-908201236).

The fix in 9002 is for `ConnectivityManager.getNetworkCapabilities` but `ConnectivityManager.registerDefaultNetworkCallback` also throws that exception and it is not handled.
