Synchronize with https://github.com/sched-ext/scx at dc44584874f0 ("kernel: Synchronize with kernel tools/sched_ext"). - READ/WRITE_ONCE() is made more proper and READA_ONCE_ARENA() is dropped. - scale_by_task_weight[_inverse]() helpers added. - Enum defs expanded to cover more and new enums. - Don't trigger fatal error when some enums are missing from kernel BTF.
