userspace: remove threads from domain on abort
When threads exited we were leaving dangling references to
them in the domain's mem_domain_q.
z_thread_single_abort() now calls into the memory domain
code via z_mem_domain_exit_thread() to take it off.
The thread setup code now invokes z_mem_domain_init_thread(),
avoiding extra checks in k_mem_domain_add_thread(), we know
the object isn't currently a member of a doamin.
