Modern mode build option

[richterdennis]

@VitalyEmelyanov requested here a modern mode build option. This is still relevant to reduce build size and improve performance in modern browsers (old browsers are still supported).

Vue CLI 3 has a new feature for build - modern mode. It creates 2 versions of scripts for modern and old browsers, linked in specific way through <script type="module">.
I'd like to see such option in quasar-cli, because it can reduce build size and improve performance in modern browsers greatly.

For newer browsers the transpiled ES5 code bundled with polyfills is unnecessary and slower then ES6+ code. Please add an option to quasar.conf, which will then if enabled create two bundles, one modern es6+ bundle and one legacy es5 bundle.

It's coming. Stay tuned.

Modern mode will be available in "@quasar/app" v1.9.

$ quasar build [....] --modern
$ quasar dev [...] --modern

# or through quasar.conf.js > build > modern: true
