tracing: Add notrace to TRACE_EVENT implementation functions
The functions used to implement the TRACE_EVENT macro show up in
function tracing. This is considered a distraction, and these should
not be displayed. For example:
<idle>-0 [000] 57.202149: task_of <-update_stats_wait_end
<idle>-0 [000] 57.202149: ftrace_raw_event_sched_stat_wait <-update_stats_wait_end
<idle>-0 [000] 57.202150: ftrace_raw_event_id_sched_stat_template <-ftrace_raw_event_sched_stat_wait
<idle>-0 [000] 57.202150: sched_stat_wait: comm=sshd pid=2735 delay=19207 [ns]
The "ftrace_raw_event_*" traces are just the utility functions used
by TRACE_EVENT tracepoints.
