Fetches the next call from the communication management and executes it.
Note: This method is only available in polling mode and aborts the process when called in event mode.
Note: ProcessNextMethodCall() will block until the returned future from the skeleton method callback is ready (value or error set to promise). Therefore, if the application is single-threaded, the method callback must ensure to return a future which is ready. A multi-threaded application may also use another thread to set the future to ready.
