Support Turbopack

I think the main blocker here is that Turbopack doesn't support a flexible enough plugin system that can fit the feature parity of unplugin. We will keep an eye on it but I think it might not happen very soon.

Curious if there's been any progress here? With Next 15 on the horizon, I'd love to leverage Turbopack but would hate to lose access to Unplugin Icons.

Looking at the Turbopack docs, I'm not seeing much movement in terms of a plugin system unfortunately.
