David Vernet 90e55164da sched_ext: Implement SCX_KICK_WAIT ...

If set when calling scx_bpf_kick_cpu(), the invoking CPU will busy wait for
the kicked cpu to enter the scheduler. See the following for example usage:

  https://github.com/sched-ext/scx/blob/main/scheds/c/scx_pair.bpf.c

v2: - Updated to fit the updated kick_cpus_irq_workfn() implementation.

    - Include SCX_KICK_WAIT related information in debug dump.
