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.
