perf, sched migration: Make it vertically scrollable
With scheduler traces covering more than two cpus, rectangles of the CPUs 3 and more are not visibles. This makes the vertical navigation scrollable so that all of the CPUs rectangles are available. We also want to be able to zoom vertically, so that we can fit at best the screen with CPU rectangles, but that's for later.
