Subject: tools: intel_gpu_analyser

This tool is intended to analyse statistics collected by intel_gpu_top and
kperf, and output summarized results for:
 - CPU usage (user and system time)
 - GPU usage (overall and per-ring)
 - Power usage in watts over time
 - Power usage relationship to CPU
 - Power usage relationship to GPU
 - Execution statistics

For perf outputs, the entire recorded perf execution is processed in
converted into a series of 'perf top'-like outputs for each process, for
each second of the execution.
