perf tools: Add processing of coresight metadata
The auxtrace_info section contains metadata that describes the number of
trace capable CPUs, their ETM version and trace configuration, including
trace id values. This information is required by the trace decoder in
order to properly decode the compressed trace packets. This patch adds
code to read and parse this metadata, and store it for use in
configuring instances of the cs-etm trace decoder.
