Summary Set serviceClass on WebRTC network connections

In Network.framework, the NWParameters.ServiceClass[^1] API can be used to enable cellular network slicing for different classes of network traffic. Like with DSCP marking for WiFi[^2], 5G cellular connection service class seems to be a good fit for WebRTC network connections where we know the type of content and latency requirements for it.
