erts: Extend process and port tracing
This commit completes the tracing for processes so that all messages sent by a process (via nifs or otherwise) will be traced. The commit also adds tracing of all types of events from ports. When enabling tracing using erlang:trace, the 'all' flag now also enables tracing on all ports. OTP-13496
