Expose `ClassValue`

[PuruVJ]

Describe the problem

Right now, if I have a component with class prop:

<script>
  const { class: className }: {class: string} = $props()
</script>

Usage:

<Comp class="py-2 sm-6" />

This works beautifully. However, with the new clsx-style classes, we should be able to type the class prop as ClassValue, basically everything that clsx supports

Describe the proposed solution

Export the ClassValue: export type ClassValue = clsx.ClassValue in svelte module, used as

import type { ClassValue } from 'svelte';

const {class: className}: { class: ClassValue[] } = $props();
