chao.an 124c1328a6 sched/note: add support of trace section mark 
The implementation of this feature is based on android systrace:

https://source.android.com/devices/tech/debug/ftrace

Application developers are more concerned about the performance of
the specified application section,
added two APIs to implement performance measurement:

void sched_note_begin(FAR const char *str);
void sched_note_end(FAR const char *str);
or
SCHED_NOTE_BEGIN();  /* defined to sched_note_begin(__FUNCTION__) */
SCHED_NOTE_END();    /* defined to sched_note_end(__FUNCTION__) */
