run: sched: rename "state" columns for cpu_frequency and cpu_capacity

Created by: derkling

CPU Frequency and Capacity trace events report the actual "frequency" and "capacity" using an anonymous "state" column. Plots generated using Plotter use that columns name in the legend, thus making a bit confusing the plot, even worst when we want to plot both frequency and capacity.

This patch assigns some more meaningful name to the "state" report by these two trace events.
