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__) */

f56aefaa41 sched_note: change uint32_t nbi_module into uint8_t array, because variables keep the same style that use uint8_t array 
sched_note: add note dump module tag definitions

NOTE_MODULE(a, b, c, d)

example:
define TEST_MODULE NOTE_MODULE('t', 'e', 's', 't')
sched_note_dump(TEST_MODULE, event, data, len);

define AUDIO_MODULE NOTE_MODULE('a', 'u', 'd', 'i')
sched_note_dump(AUDIO_MODULE, event, data, len);

d05b9a9c79 note dump: add CONFIG_SCHED_INSTRUMENTATION_SWITCH 
1. If CONFIG_SCHED_INSTRUMENTATION_SWITCH is enabled, then these additional interfaces are expected:
        sched_note_suspend
        sched_note_resume
at the same time，If CONFIG_SMP is enabled，then expected：
        sched_note_cpu_pause
        sched_note_cpu_paused
        sched_note_cpu_resume
        sched_note_cpu_resumed
2. other board if enable SCHED_INSTRUMENTATION，SCHED_INSTRUMENTATION_SWITCH to defconfig.
