Custom themes support

We use windicss in our project (and love it), and would like to add a high contrast theme. There’s currently support for the dark theme, but would it be possible to add a custom theme in windicss’s config file? Then do something like:

<button class=“bg-green-400 dark:bg-green-500 high-contrast:bg-green-600”>My button with high contrast support</button>

Proposed API

export default defineConfig({
  darkMode: 'class', // deprecate this in v4 (or not if we want to maintain compatibility with tailwind)
  colorSchemes: {
    dark: 'media', // possible values are same as `darkMode` above
    'high-contrast': true, // possible values would be `true` or `false`
    'neon': false
    // and so on
  }
})

I propose that this be the new API to add more color schemes to the configuration.

Would this be fine?

@IgnisDa haven’t got any feedback of the rest of the team. Probably not deprecating the darkMode field would be better. But otherwise the proposal looks good for me. I think you can make a PR and then post your RFC in there, you might expect to get some questions and change the API. 😃
