[canvaskit] Start a generic puppeteer perfing system. IMPORTANT LESSON: when bringing in node (and possibly other executables) via CIPD, add them to the path in gen_tasks_logic so the parent executable (the task driver itself) has the right PATH set. Otherwise, the subprocesses it spawns might grab the wrong version because of how golang handles environments of subprocesses. This is starting as a fork of Skottie WASM. I hope to have a more unified system for creating and running benchmarks. Overall overview: gen_tasks_logic.go creates a task in task.json that compiles CanvasKit and the task drivers and then executes our task (i.e. perf_puppeteer.go) perf_puppeteer runs a node program (perf-with-puppeteer.js) that uses puppeteer to execute benchmarking code on an html page (canvaskit-skottie-frames-load.html). I needed to update the node package so npm could be updated from 3.x to 6.14.4 so it knew about `npm ci`. This may not have been entirely necessary, given the problems of executing the correct npm (see important lesson above), but it hasn't broken things further, so more up-to-date is probably a good thing. Suggested Review Order: - canvaskit-skottie-frames-load.html (note it is similar to skottie-wasm-perf.html, but it waits for a button click to start animating and records times from the main JS thread itself) - perf-with-puppeteer.js (similar to skottie-wasm-perf.js, but has some things made optional [e.g. tracing]) - perf_puppeteer_test.go (shows the inputs/outputs of various steps) - perf_puppeteer.go - Everything else.
