Add a newer, much smaller and simpler implementation of abort and join. No need to involve the idle thread. No need for a special code path for self-abort. Joining a thread and waiting for an aborting one to terminate elsewhere share an implementation. All work in both calls happens under a single locked path with no unexpected synchronization points. This fixes a bug with the current implementation where the action of z_sched_single_abort() was nonatomic, releasing the lock internally at a point where the thread to be aborted could self-abort and confuse the state such that it failed to abort at all. Note that the arm32 and native_posix architectures, which have their own thread abort implementations, now see a much simplified "z_thread_abort()" internal API.
