Description

Qwik already supports css files and css modules. Vite out of the box supports sass and scss files along with their module counterparts. This change enables the usage of SASS files and SASS modules.

Use cases and why

• 1. .scss and .sass files even though correctly processed by Vite, are never properly exposed. Even though class names are properly created by css-modules through *.module.scss files, the actual stylesheets are unavailable to the components. This change let Qwik properly utilise styles transpiled by Vite.
