[PATCH v3 5/9] perf mem: Support AUX trace

[Leo Yan]

Perf memory tool doesn't support AUX trace data so it cannot receive the
hardware tracing data.  On Arm64, although it doesn't support PMU events
for memory load and store, but Arm SPE is a good candidate for memory
profiling, the hardware tracer can record memory accessing operations
with affiliated information (e.g. physical address and virtual address
for accessing, cache levels, TLB walking, latency, etc).

To allow "perf mem" tool to support AUX trace, this patches adds the AUX
callbacks for session structure.
