Tejun Heo 9b671793c7 sched_ext, scx_qmap: Add and use SCX_ENQ_CPU_SELECTED ... scx_qmap and other schedulers in the SCX repo are using SCX_ENQ_WAKEUP to tell whether ops.select_cpu() was called. This is incorrect as ops.select_cpu() can be skipped in the wakeup path and leads to e.g. incorrectly skipping direct dispatch for tasks that are bound to a single CPU. sched core has been updated to specify ENQUEUE_RQ_SELECTED if ->select_task_rq() was called. Map it to SCX_ENQ_CPU_SELECTED and update scx_qmap to test it instead of SCX_ENQ_WAKEUP.
