ipynb/examples/Idle: Add extra idle state analysis

- Use cpuidle devlib module to poke CPUs to make sure cpu_idle events
  are present in the trace
- Set performance cpufreq governor to make sure there are idle periods
  during workload execution
- Pin workload to CPU 1
- Make workload period shorter and extent duty cycle range to extend
  over full idle state target residency range.
- Add an ILinePlot of the cpuidle state showing how the idle state used
  gets deeper as the workload duty cycle decreases in length.
- Add a histogram and scatter plot of idle period lengths
