Add a search option to the Menu module like what we have on the theme

In the theme, we have the option to show a search box. This would add similar functionality to the menu module.

I can’t even find this in the theme… but HECK YES. I’m finding it way harder to add a search bar than it should be using Beaver Themer to replace my header.

Yes, I saw the forum mentioning using an HTML module plus a custom shortcode, but that’s very out of the way (and I can’t get it to line up for anything) for what should be a setting on the menu module.
