[IMP] tags: reintroduce inline css tag

Browse Source 
The CSS tag is useful to define a css stylesheet in the javascript file:
```js
class MyComponent extends Component {
  static template = xml`
        <div class="my-component">some template</div>
    `;
  static style = css`
    .my-component {
      color: red;
    }
  `;
}
```

The `css` tag registers internally the css information. Then, whenever the first instance of the component is created, will add a <style> tag to the document <head>.
