Cleanup after #5310 (SPU thread groups)

Move lambda into a cpu_stop()
Use running thread counter to synchronize with sys_spu_thread_group_join()
Use SPU_STATUS_STOPPED_BY_STOP exclusively for sys_spu_thread_exit() as before
Remove unnecessary waiting in sys_spu_thread_group_exit()
Rollback some minor unnecessary changes
Use shared_mutex in SPU TG
