support rolldown in node-adapter

[TorstenDittmann]

Describe the problem

Now with https://voidzero.dev/posts/announcing-rolldown-vite being a thing, i am trying to adopt rolldown in my svelte kit application and it required me to change the node-adapter, by replacing rollup + plugins with just rolldown for the sweet extra performance.

Describe the proposed solution

Not sure what the best solution would be here:

• giving the user an option to choose between rollup/rolldown
• create a preview version that replaces rollup with rolldown (would make most sense to me)
• create a separate adapter using rolldown

Alternatives considered

Using a patched version of the node-adapter for now.

This is what I have been using, more than happy to raise the PR against the rolldown branch for #13747 if there is interest 👍🏻
