Trace perf: power metric uWs/frame -> W, exclude startup&teard Switching from uWs/frame to W, which is easier to measure as we don't need to know how many frames were rendered between the measurements and just need to avoid warmup, turndown. Also, W is a more "natural" metric as it reports actual power usage that can be reasoned about in terms of device thermals etc. Changing starting point to post-warmup by waiting for test message in logcat. The logcat -> script delay seems very small in my tests. Turndown also shows spikes in some traces so avoiding that by shifting the time for end point collection to 1s before the test is expected to finish (which makes this only compatible with --fixedtime) Also made device selection set env var instead of a global variable and passing via args it slighlty simplifies subprocess(adb) handling.
