Support lightningcss "resolver" option about vite

[bluwy]

What is the usecase for accepting a resolver option? Vite has its own internal resolver too and it should use that. Similar to how postcss-import and CSS preprocessors like SCSS, Stylus, all use Vite's resolver only.

The idea is to allow use of globs into the css @import like so:

@import './components/**/*.css';

For now it's not working at all.
I checked with the lightningcss repo contributors parcel-bundler/lightningcss#735 but they think it's on the vite side.

If I check the postcss-import-ext-glob plugin https://github.com/dimitrinicolas/postcss-import-ext-glob/blob/master/index.js, it's inside the postcss AST that the support is added.

My guess is that the simpliest way to allow devs to support custom imports inside the lighningcss module is to pass the resolver options down to lighntningcss from the lighningcss options object like in my example above.

Unless you have another idea that I will be happy to implement and share :)

In that case, it seems like a bug (or technically a feature request) to me to make import globs work with lightningcss. There's also a corresponding postcss feature request: #12336. If we can get this working, then I don't think we have to expose the resolver option.
