Fix Vite not being able analyze dynamic CSS styles import in dev

Browse Source 
Fix:
```
$ yarn start
[vite] warning:
@theme/default
1  |  import "C:\Users\MLM\Documents\GitHub\element\hydrogen-web\src\platform\web\ui\css\themes\element\theme.css";import "@theme/element/light/variables.css"
   |          ^
The above dynamic import cannot be analyzed by vite.
See https://github.com/rollup/plugins/tree/master/packages/dynamic-import-vars#limitations for supported dynamic import formats. If this is intended to be left as-is, you can use the /* @vite-ignore */ comment inside the import() call to suppress this warning.

  Plugin: vite:import-analysis
  File: @theme/default
```

And in the browser, it results in none of the styles loading because of the following error:
```
Uncaught SyntaxError: Invalid Unicode escape sequence (at default:formatted:1:163)
```

---

Before:
```
import { injectQuery as __vite__injectQuery } from "/@vite/client";import "__vite__injectQuery(C:\Users\MLM\Documents\GitHub\element\hydrogen-web\src\platform\web\ui\css\themes\element\theme.css, 'import')";import "/@id/__x00__@theme/element/light/variables.css"
```

After:
```
import "/ui/css/themes/element/theme.css";import "/@id/__x00__@theme/element/light/variables.css"
```

* To load the theme during dev, we need to take a different approach because emitFile is not supported in dev.
* We solve this by resolving virtual file "@theme/name/variant" into the necessary css import.
