perf: Add 'perf sched' tool
This turn-key tool allows scheduler measurements to be conducted and the results be displayed numerically. First baby step towards that goal: clone the new command off of perf trace. Fix a few other details along the way: - add (minimal) perf trace documentation - reorder a few places - list perf trace in the mainporcelain list as well as it's a very useful utility.
