Actually I think "type": "module" syntax detection is required for performance issue. Node.js doc says, "Syntax detection should have no performance impact on CommonJS modules, but it incurs a slight performance penalty for ES modules; add "type": "module" to the nearest parent package.json file to eliminate the performance cost." That is why I think may be we may add this here.

The root package.json is only for dev time, but it's nice to have.

…s node mode (#4979)

#4974 broke the tests because
`type: module` makes the bundle to use node mode.

This PR adds an empty `package.json` under `crates/rolldown/tests` to
prevent esbuild to treat all files as node mode.
