7dfbd14eba libc: add instrument api support 
Add registration function instrumentation API,
which can achieve instrumentation of entering and
exiting functions through the compiler's functionality.

We can use CONFIG_ARCH_INSTRUMENT_ALL to add instrumentation for all
source, or add '-finstrument-functions' to CFLAGS for Part of the
source.

Notice:
1. use CONFIG_ARCH_INSTRUMENT_ALL must mark _start or entry noinstrument_function,
   becuase bss not set.
2. Make sure your callbacks are not instrumented recursively.

use instrument_register to register entry function and exit function.
They will be called by the instrumented function

c3009d46e9 note: delete sched_note_flatten 
When we record data and dump data, they are all executed within the system,
and there is no need to consider the issue of big or small endianness.
