Allow to use node-resolve as a standalone module

[raythurnvoid]

• Rollup Plugin Name: plugin-node-resolve
• Rollup Plugin Version: 13.0.0

Feature Use Case

As for now https://github.com/browserify/resolve doesn't support ESM fields (imports, exports), this is a problem for other tools including Vite which depends on it to resolve imports in SSR. I've opened an issue to Vite vitejs/vite#3953 to ask them if it is possible to replace it with https://github.com/webpack/enhanced-resolve.
This solves the issue but i find https://github.com/webpack/enhanced-resolve implementation quite hard maintain while plugin-node-resolve on the other hand is much simpler.

Feature Proposal

I would like to know if it is possible to merge implementation with https://github.com/browserify/resolve or if it's possible to create a standalone function that can be called outside of the rollup context (so without depending on the this valorized by rollup)

A good start to this would be to expose/re-export resolveImportSpecifiers in node-resolve index.js:
