[New Feature] Add Util function to merge classes and merge all files to use the util

[kotAPI]

🚀 Feature Request

Feature Description

We currently apply classes to our components this way

className = `${rootClassName} ${className}`

Where we end up with empty spaces in class strings when a value isn't available.

<div class="rootclass "></div>

sometimes there's also a risk of className being undefined
which causes our classes to look like this

<div class="rootclass undefined"></div>

Using tools like clsx or any other utils can help with this

https://www.npmjs.com/package/clsx

This will also require us to refactor most of our components
