df30a1f8d3 sched/pthread/join: refactor pthread join to support join task
1. add support to join main task

| static pthread_t self;
|
| static void *join_task(void *arg)
| {
|   int ret;
|   ret = pthread_join(self, NULL);          <---  /* Fix Task could not be joined */
|   return NULL;
| }
|
| int main(int argc, char *argv[])
| {
|   pthread_t thread;
|
|   self = pthread_self();
|
|   pthread_create(&thread, NULL, join_task, NULL);
|   sleep(1);
|
|   pthread_exit(NULL);
|   return 0;
| }

2. Detach active thread will not alloc for additional join, just update the task flag.
3. Remove the return value waiting lock logic (data_sem),
   the return value will be stored in the waiting tcb.
4. Revise the return value of pthread_join(), consistent with linux
   e.g:
       Joining a detached and canceled thread should return EINVAL, not ESRCH

   https://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_join.html

   [EINVAL]
      The value specified by thread does not refer to a joinable thread.

NOTE:

This PR will not increase stack usage, but struct tcb_s will increase 32 bytes.

fc9f87824c sched/pthread: Return ESRCH when the task is in the process of exit.
Resolving the issue with the ltp_interfaces_pthread_join_6_2 test case.

In SMP mode, the pthread may still be in the process of exiting when
pthread_join returns, and calling pthread_join again at this time will
result in an error. The error code returned should be ESRCH.
