[feat]: Support combobox with many items

[kenn]

Feature description

Combobox gets really slow when you have many items in it. In my case with 5,000 items, it takes full 2 seconds just to open the Popover / Drawer.

Headless UI v2.0 introduced new combobox using TanStack Virtual, which can handle 100,000+ items.

Would you consider incorporating the same idea?

It may be harder to implement, but I do think supporting a large list is essential for combobox — there's no better UI to deal with large-ish (~1MB in local storage) lists.

But it comes with additional complexity, so clearly it's a trade-off. I'm fine if this is out of scope for this library, but just would love to hear the decision clearly, not closed due to inactivity.
