tracing: Remove notrace from trace_event_raw_event_synth()

When debugging the synthetic events, being able to function trace its
functions is very useful (now that CONFIG_FUNCTION_SELF_TRACING is
available). For some reason trace_event_raw_event_synth() was marked as
"notrace", which was totally unnecessary as all of the tracing directory
had function tracing disabled until the recent FUNCTION_SELF_TRACING was
added.

Remove the notrace annotation from trace_event_raw_event_synth() as
there's no reason to not trace it when tracing synthetic event functions.
