perf tools: Add user events for AUX area tracing
Add two user events for AUX area tracing.
PERF_RECORD_AUXTRACE_INFO contains metadata, consisting primarily the
type of the AUX area tracing data plus some amount of
architecture-specific information. There should be only one
PERF_RECORD_AUXTRACE_INFO event.
PERF_RECORD_AUXTRACE identifies AUX area tracing data copied from the
mmapped AUX area tracing region. The actual data is not part of the
event but immediately follows it.
