d7f02a8cb6 sched: change pthread_mutex implementation from sem to mutex 
Since pthread_mutex is implemented by sem, it is impossible to see in ps who holds the lock and causes the wait.
Replace sem with mutex implementation to solve the above problems

4c8d244fae sched/getpid: replace syscall getpid/tid/ppid() to kernel version 
NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.
