tracing: Move sched event insertion helpers in the sched switch tracer file
The sched events helpers which insert the sched switch and wakeup
events into the ring buffer currently reside in trace.c
But this file is quite overloaded and the right place for these helpers
is in the sched switch tracer file.
Then move them to trace_functions.c
