perf scripts python: intel-pt-events.py: Fix printing of switch events

commit 0f80bfbf4919e32f52fe1312c3900ff4fbb7eeb9 upstream.

The intel-pt-events.py script displays only the last of consecutive switch
statements but that may not be the last switch event for the CPU. Fix by
keeping a dictionary of last context switch keyed by CPU, and make it
possible to see all switch events by adding option --all-switch-events.
