@ealmloff I would like to introduce a new component to the Dioxus collection.

[ealmloff]

We need keyboard support for drag and drop before we can add this to dioxus primitives. https://react-aria.adobe.com/dnd#accessibility and the kanban board example might be useful as a reference. They let you select drag and drop elements with enter, move them with arrow keys and then drop them with enter

@ealmloff I added the ability to move elements using the keyboard

I've added a separate class for icons.
If you give me the go-ahead, I'll reuse this class in the future (as a separate MR) across all source files.

I find this implementation useful for several reasons:

1. All icons are mostly created with the same parameters, meaning that only the internal content changes, which is sufficient to pass to the component. This will also help avoid excessive code duplication.
2. I looked at the spinner implementation from shadcn; it also uses icons, so this will essentially be the first step in implementing such a component. Later, by adding a simple animation, we'll have another component with minimal effort.
3. In the future, if we want to create our own icon collection, this class will become a reliable foundation.

Yes, that would be much nicer
