chao.an 6e0ba2bed5 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(uintptr_t ip, FAR const char *buf);
void sched_note_end(uintptr_t ip, FAR const char *buf);
or
SCHED_NOTE_BEGIN();  /* defined to sched_note_begin(_THIS_IP_, __FUNCTION__) */
SCHED_NOTE_END();    /* defined to sched_note_end(_THIS_IP_, __FUNCTION__) */
