Update to make sure AMP only bundles are always removed in production

[ijjk]

In development we require the page's bundle in the hot-reloader to check the page config and ensure we 404 properly for AMP only client bundles. This makes sure we also use the page config from requiring the bundle during a production build to also make sure we remove any AMP only client bundles.

This fixes development and production mismatching behavior although was uncovered from the next-page-config babel transform not detecting the below export syntax. Since the transform there is mainly an optimization at this point and no longer required for detecting it can be updated in a follow-up PR after deciding which syntaxes should be supported for static analysis other than the normal export const config = {...}.

const config = {...}
export { config }

Closes: #11521
