Andrew Boie 8eaff5d6d2 k_thread_abort(): assert if abort essential thread
Previously, this was only done if an essential thread self-exited,
and was a runtime check that generated a kernel panic.

Now if any thread has k_thread_abort() called on it, and that thread
is essential to the system operation, this check is made. It is now
an assertion.

_NANO_ERR_INVALID_TASK_EXIT checks and printouts removed since this
is now an assertion.
