ref(nuxt): Only use rollup for build (#13138)

Previously, the Nuxt SDK was built with `@nuxt/module-builder` and
rollup. This made things complicated, as it created two separate folders
in the build output which could not share code between each other.

This setup removes the `@nuxt/module-builder` and adds the module config
to rollup.
