Webpack has some simple but useful options for specifying performance limits. This patch enables asset and entry point (+ all dependencies) filesize requirements for production builds. This helps us track minified but uncompressed filesizes which are reported by mw.loader.inspect() (including CSS). https://webpack.js.org/configuration/performance/ Bug: T165036 Change-Id: I331ff34f50270be2912fd8cef5219cafc6957e80
