perf sched: Add support for sched:sched_stat_runtime events

This allows more precise 'perf sched latency' output:

 ---------------------------------------------------------------------------------------
  TOTAL:                | 2079.078 ms |      153 |
 -------------------------------------------------

Also, streamline the code a bit more, add asserts for various state
machine failures (they should be debugged if they occur) and fix
a few odd ends.
