K Prateek Nayak 4b87406a3b perf stat record: Save cache level information 
When aggregating based on cache-topology, in addition to the aggregation
mode, knowing the cache level at which data is aggregated is necessary
to ensure consistency when running 'perf stat record' and later 'perf
stat report'.

Save the cache level for aggregation as a part of the env data that can
be later retrieved when running perf stat report.
