German Gomez 27d113cfe8 perf arm-spe: Support hardware-based PID tracing
If ARM SPE traces contains CONTEXT packets with TID info, use these
values for tracking the TID of samples. Otherwise fall back to using
context switch events and display a message warning to the user of
possible timing inaccuracies [1].
