Expose an application's total execution time as a percentage of CPU/GPU. #1300

Could imagine stats:

  1. Total app time: 30% of app's time is GPU 70% of app's time is CPU
  2. CPU/GPU throughput: 80% of total CPU throughput is consumed by this app 20% of total GPU throughput is consumed by this app

The first should be fairly easy. Kenzie suggested that current FPS should be displayed with %GPU as well (first one "Total app time").

The second one, seems hard unless we have some way of knowing for each GPU/CPU type what is the (max cycles / time period) or if there is a test we could run to find what pegging the CPU/GPU means to known how much of CPU/GPU is being used by this app.

https://github.com/flutter/flutter/issues/33899 is the related Flutter issue. We think that CPU/GPU percentage is a nice estimation for the energy use, which is a crucial performance issue to mobile devices.
