Reland Implement Skottie vs Lottie perf tool

Add PerfActivity to Skottie demo app, which can render
with both Lottie and Skottie players. Create bash script, which
runs 15 lottie files with both renderers, runs perfetto and
outputs performance metrics in json files.

Test: ran run_perf.sh and it outputs perf metrics on WearOS and Android
