since the standard require the caller pass the name explicitly
https://pubs.opengroup.org/onlinepubs/009695399/functions/posix_spawn.html:
The argument argv is an array of character pointers to null-terminated strings.
The last member of this array shall be a null pointer and is not counted in argc.
These strings constitute the argument list available to the new process image.
The value in argv[0] should point to a filename that is associated with the
process image being started by the posix_spawn() or posix_spawnp() function.

It's better to save one argument by returning pid directly.
This change also follow the convention of task_create.
BTW, it is reasonable to adjust the function prototype a
little bit from both implementation and consistency since
task_spawn is NuttX specific API.

But let nuttx/sched.h include sched.h instead to
avoid expose nuttx kernel API to userspace.

All modern desgin support stack pointer and it's also an
important information, so let's standardize this interface.

since emergstream always call syslog_force, but syslog_force is designed
for the interrupt context, and then doesn't mean any emergency thing.
On the other hand, emergstream has other bad side effect:
1.Can't output to file or dev channel
2.Can't work well with the interrupt buffer

Repetition step:
If using waitpid() to wait a task has exited, the waitpid will use
nxsing_kill with signal number 0 to determine if that task is still
alive, and will call group_signal to dispatch signal for each member
of the group and perform signal handing checks, it will assert at
