Telemetry: remove old cpu_per_frame metrics by chiniforooshan@chromium.org

This is expected. We changed the definition of frame from renderer compositor frame to display compositor frame in this metric. So, thread_*_cpu_time_per_frame should roughly change proportional to

frame_times / mean_frame_time_renderer_compositor

In this case, the above ratio is 18.301 / 55.21 = 0.3314, which is pretty close to the new value / old value of the metric, i.e. 31.05 / 91.69 = 0.3386.
