feat(@angular/cli): add scope hoisting via webpack 3

This should result with significant bundle size reduction.

See https://medium.com/webpack/webpack-3-official-release-15fd2dd8f07b for details.

`--vendor-chunk` now defaults to `false` on `--prod` builds. This was changed because the separate vendor bundle affected potential size reduction from adding scope hoisting, so it became sub-optimal to use a vendor bundle when deploying to production.
