perf auxtrace: Add support for queuing AUX area samples
Add functions to queue AUX area samples in advance (auxtrace_queue_data()) or individually (auxtrace_queues__add_sample()) or find out what queue a sample belongs on (auxtrace_queues__sample_queue()). auxtrace_queue_data() can also queue snapshot data which keeps snapshots and samples ordered with respect to each other in case support for that is desired.
