fb9be71e - Add clearer documentation for asynchronous I/O to the manual. (#35412)

Add clearer documentation for asynchronous I/O to the manual. (#35412) This adds a section to the end of the "networking and streams" page that explicitly mentions asynchronous I/O and provides a couple of code examples using the @sync / @async macros. It uses a Sockets-based example for demonstrating the usage of the @sync / @async macros, since it does a better job of demonstrating the asynchronous nature of I/O functions.
