[PATCH v4 sched_ext/for-7.3 06/40] sched_ext: Rename extra_enq_flags to remote_activate_enq_flags

scx_rq.extra_enq_flags carries scx-specific enqueue flags across the
activate_task() boundary during a cross-rq task move in
move_remote_task_to_local_dsq(). Rename it to remote_activate_enq_flags to
name that role, and fix the stale comment that referenced the old
move_task_to_local_dsq() name.

No functional change.
