New setting cjsInterop

[brillout]

Description

// vike.config.js

export default {
  fixNpmPackages: ['some-npm-package']
}

Vike would then:

• If some-npm-package is CJS add it to https://github.com/cyco130/vite-plugin-cjs-interop.
• Otherwise, add it to ssr.noExternal.
• Show a warning saying that "Please reach out to the some-npm-package maintainer with a reproduction".

TODO: Vite currently fails when adding a CJS package to ssr.noExternal, check whether Vite has plans to support executing CJS server-side code.

Edit: a new config cjsInterop would probably be better. Setting it to true would automatically apply it (by dynamically checking whether a package is CJS).
