The existing version of defaultTriggerAsyncIdScope creates an Array for the callback's arguments which is highly inefficient. Instead, use rest syntax and allow V8 to do that work for us. This yields roughly 2x performance for this particular function.

This allows more easy tracking of where HTTP requests come from. Before this change the HTTPParser would have the HTTPServer as the triggerAsyncId. The HTTPParser will still have the executionAsyncId set to the HTTP Server so that information is still directly available. Indirectly, the TCP socket itself also has its triggerAsyncId set to the TCP Server.

If IPv6 is not supported on a machine, the IPv6 handle will first be created, this will then fail and default to an IPv4 handle. This causes the graph to change, as there now is an extra handle.
