tocss: Add vars option
This commit adds a new `vars` option to both the Sass transpilers (Dart Sass and Libsass).
This means that you can pass a map with key/value pairs to the transpiler:
```handlebars
{{ $vars := dict "$color1" "blue" "$color2" "green" "$font_size" "24px" }}
{{ $cssOpts := (dict "transpiler" "dartsass" "outputStyle" "compressed" "vars" $vars ) }}
{{ $r := resources.Get "scss/main.scss" | toCSS $cssOpts }}
```
And the the variables will be available in the `hugo:vars` namespace. Example usage for Dart Sass:
```scss
@use "hugo:vars" as v;
p {
color: v.$color1;
font-size: v.$font_size;
}
```
Note that Libsass does not support the `use` keyword, so you need to `import` them as global variables:
```scss
@import "hugo:vars";
p {
color: $color1;
font-size: $font_size;
}
```
Hugo will:
* Add a missing leading `$` for the variable names if needed.
* Wrap the values in `unquote('VALUE')` (Sass built-in) to get proper handling of identifiers vs other strings.
This means that you can pull variables directly from e.g. the site config:
```toml
[params]
[params.sassvars]
color1 = "blue"
color2 = "green"
font_size = "24px"
image = "images/hero.jpg"
```
```handlebars
{{ $vars := site.Params.sassvars}}
{{ $cssOpts := (dict "transpiler" "dartsass" "outputStyle" "compressed" "vars" $vars ) }}
{{ $r := resources.Get "scss/main.scss" | toCSS $cssOpts }}
```
Fixes #10555
