This PR adds support for the `blocklist` config option when using a JS
config file in v4. You can now block certain classes from being
generated at all. This is useful in cases where scanning files sees
things that look like classes but are actually not used. For example, in
paragraphs in a markdown file:
```js
// tailwind.config.js
export default {
blocklist: ['bg-red-500'],
}
```
```html
<!-- index.html -->
<div class="bg-red-500 text-black/75"></div>
```
Output:
```css
.text-black/75 {
color: rgba(0, 0, 0, 0.75);
}
```
