Many of us are running a watchdog in the background that keeps `//lib` folder up-to-date, so there's no need to re-build Playwright from source on every `npm install` command. This patch does a crude timestatmp comparison between typescript files and their javascript counterparts. If some files are missing in `//lib`, or if some `//src` files are newer than `//lib`, then it re-builds the Playwright. This cuts off 10 seconds for me on in case I have a watchdog in the background.
