A new BPF extensible sched_class will use css_tg() in the init and exit
paths to visit all task_groups by walking cgroups.
v4: __setscheduler_prio() is already exposed. Dropped from this patch.
v3: Dropped SCHED_CHANGE_BLOCK() as upstream is adding more generic cleanup
mechanism.
v2: Expose SCHED_CHANGE_BLOCK() too and update the description.
