  Traces: Add restricted_trace_perf.py script for Android
  
  We've been using restricted_trace_perf.py to gather numbers on
  Android devices. The script uses angle_perftests and records:
  
  - Wall time per frame
  - GPU time per frame
  - CPU time per frame
  - GPU power per frame
  - CPU power per frame
  - GPU memory per frame
  
  It reports numbers to the terminal and creates a spreadsheet at
  the end. A typical command to run it would be:
  
    python3 restricted_trace_perf.py --fixedtime 10 --power \
      --output-tag <tag> --loop-count 5
  
  Power numbers are only available on Pixel 6 as we read directly
  from power rails.
  
  Also included is a gpumem shell script run on the Android device,
  and a power_denoising script that deactivates a number of services
  to reduce variance. The former is invoked automatically, the latter
  is only invoked by hand.
