sched_ext: Document the rolling-cursor requirement for dsq_vtime
scx_bpf_dsq_insert_vtime() orders tasks by time_before64(), which is
only meaningful when the values within a given DSQ stay less than 2^63
apart. This is implicit in how a vtime scheduler works but not spelled
out anywhere. Document it so BPF scheduler authors know the
constraint.
