Skip the child wait if here is only self in member list,
since the members of the task group should be 1 if task exit.

Change the type of task group member to single list chain to
avoid accessing the memory allocator to improve the performance

This moves task / thread cancel point logic from the NuttX kernel into
libc, while the data needed by the cancel point logic is moved to TLS.
The change is an enabler to move user-space APIs to libc as well, for
a coherent user/kernel separation.
Do not allow a deferred cancellation if the group is exiting, it is too
dangerous to allow the threads to execute any user space code after the
exit has started.
If the cancelled thread is not inside a cancellation point, just kill it
immediately via asynchronous cancellation. This will create far less
problems than allowing it to continue running user code.
Summary:
- During testing iperf -s with lc823450-xgevk:rndis,
I noticed that hard fault happens
- Finally, I found that group_kill_children() is not
not protected by a critical section
- This commit fixes this issue
Impact:
- SMP only
Testing:
- Tested with iperf with the following configurations
- lc823450-xgevk:rndis, spresense:rndis_smp
- Tested with ostest with the following configurations
- lc823450-xgevk:rndis, esp32-devkitc:smp (QEMU)
- sabre-6quad:smp (QEMU), maix-bit:smp (QEMU)
- spresense:rndis_smp, sim:smp
