Dedicated Sass language service support

[niksy]

Mentioned in language tools: vuejs/language-tools#4111

Based on standalone Sass language server.

Would be nice to have dedicated Sass language service support. Any tips on how to get started?

I'll just note that adding support for things like that would need extra resources to maintain and those are already low.

Personally I would prefer if Volar focused on core functionality and not support plugins like prettier,sass or emmet. History shows that there is enough things to work on in the core functionality.

And BTW. It's already possible to set up SASS language server (there are extensions or packages that can be used here).

PR welcome! Have a look at https://github.com/volarjs/services/blob/master/packages/json for inspiration. It looks like these are the features you need to implement.
