trace_processor: Add cpuidle state residences

Introduce cpuidle states cpu_counter_tracks. Counter tracks are named
cpuidle.{state}, with the state name determined by
/sys/devices/system/cpu/cpu*/cpuidle/state*/name.

Bug: 337135369
Test: build trace_processor locally, run a trace with `cpuidle_period_ms` enabled and check counters/cpu_counter_tracks
Test: diff tests
