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.

@ -8,3 +8,17 @@ ToDos sorted by priority:
- 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.
