perf report: Parse time quantum
Many workloads change over time. 'perf report' currently aggregates the
whole time range reported in perf.data.
This patch adds an option for a time quantum to quantisize the perf.data
over time.
This just adds the option, will be used in follow on patches for a time
sort key.
