perf sched: Add 'perf sched map' scheduling event map printout
This prints a textual context-switching outline of workload
captured via perf sched record.
For example, on a 16 CPU box it outputs:

Columns stand for individual CPUs, from CPU0 to CPU15, and the
two-letter shortcuts stand for tasks that are running on a CPU.
'*' denotes the CPU that had the event.
A dot signals an idle CPU.
New tasks are assigned new two-letter shortcuts - when they occur
first they are printed. In the above example 'T1' stood for irqbalance:
T1 => irqbalance:2089
