  tools/sched_ext: Sync with scx repo (2025-04-02 09:08:33 -1000)

----------------------------------------------------------------
sched_ext: Fixes for v6.15-rc0

- Calling scx_bpf_create_dsq() with the same ID would succeed creating
  duplicate DSQs. Fix it to return -EEXIST.

- scx_select_cpu_dfl() fixes and cleanups.

- Synchronize tool/sched_ext with external scheduler repo. While this isn't
  a fix. There's no risk to the kernel and it's better if they stay synced
  closer.
