Adding Icon component for external libs

Implementation of the <Icon /> component which makes it easier to create (custom) icons from iconNodes.
This will be useful for external packages like @lucide/lab and more.

Example with lucide-react

import { burger } from '@lucide/lab';
import { Icon } from 'lucide-react';

<Icon iconNode={burger} /> // Renders burger icon
