Alan Agius ce15899020 feat(@angular-devkit/build-angular): use sass instead of node-sass
BREAKING CHANGE: we no longer use `node-sass` by default, instead we use `sass` (dart-sass).

While in most cases this should not have an impact the generated code, dart sass has some differences from Ruby Sass. See https://github.com/sass/dart-sass#behavioral-differences-from-ruby-sass for more details

If you wish to use `node-sass` instead of `sass` you need to install node-sass as a dev dependency.

npm users
```
npm install node-sass --save-dev
```

yarn users
```
yarn add node-sass --dev
```

**Note:** for larger Sass projects to avoid this performance hit you might want to install `fibers`. See: https://www.npmjs.com/package/fibers
