Implement DOMWidget for vue (#6006)

![vue-dom-widget](https://github.com/user-attachments/assets/d0c0e5f6-bacb-4fd9-957e-4f19e8071c3d)

Did testing on about a dozen custom nodes. Most just work.
- Some custom nodes have copy/pasted the `addDOMWidget` call with types
like `customtext` and get converted to textareas -> Not feasible to fix
here. Can open PRs into custom nodes if complaints arise.
- Only the KJNodes spline editor had mouse issues -> Can
investigate/open PR into KJNodes later.
- Many nodes don't resize gracefully. Probably best handled in a future
PR.
- Some expect to be handled like textareas. These currently have minsize
and don't scale.
- Others, like VHS previews, scale self properly, but don't update
height inside a drag operation -> node height can be set to less than
fit.
