This PR closes #592 by making the .css rule also process .postcss files when Encore.enablePostCssLoader() has been called.

It seems that it can be useful in a Vue.js context in order to have proper syntax highlighting in IDEs by using lang="postcss", as explained on https://vue-loader-v14.vuejs.org/en/features/postcss.html:

Since vue-loader handles PostCSS on its styles internally, you only need to apply postcss-loader to standalone CSS files. There's no need to specify lang="postcss" on a style block if there is a PostCSS config file in your project.

Sometimes the user may want to use lang="postcss" only for syntax highlighting purposes.
