perf record: Add support for AUX area sampling
Add a 'perf record' option '--aux-sample' to request AUX area sampling.
AUX area sampling uses an overwriting buffer much like snapshot mode, so
adjust the AUX buffer mmapping accordingly. To make it easy to queue
samples for decoding, synthesize an ID index.
