cpupower: ToDo: Update ToDo with ideas for per_cpu_schedule handling 



Based on Thomas Renninger's feedback/ideas. Re-structure the code
to better handle the per_cpu_schedule mechanism which was introduced
when adding support for AMD Zen based processors.

- Add another c1e debug idle monitor

  -> Is by design racy with BIOS, but could be added

     with a --force option and some "be careful" messages

- Add cpu_start()/cpu_stop() callbacks for monitor

  -> This is to move the per_cpu logic from inside the

     monitor to outside it. This can be given higher

     priority in fork_it.

- Fork as many processes as there are CPUs in case the

  per_cpu_schedule flag is set.

  -> Bind forked process to each cpu.

  -> Execute start measures via the forked processes on

     each cpu.

  -> Run test executable in a forked process.

  -> Execute stop measures via the forked processes on

     each cpu.

  This would be ideal as it will not introduce noise in the

  tested executable.
