Add a component for custom selects

[titouanmathis]

It should help to easily create custom <select> form elements with accessibility in mind.

The Menu component can already manage dropdowns, maybe extend it to synchronize values with a <select>.

See https://ui.studiometa.dev/-/components/molecules/Menu/examples.html#dropdown

Extend the Menu component is a great idea because it already include the focus trap that is missing in your codepen @titouanmathis

This require more work than extending the Menu component to do it properly and respect the WCAG guidelines for combobox.
