 * Returns onResponse and onRequest fetch interceptors that will bubble
 * cacheability from the response to the current request event.
 *
 * The onResponse interceptor will merge CDN headers from CDN cached API routes
 * to the current request and merge them.
 *
 * If the route cache is enabled, the onResponse interceptor will also bubble
 * maxAge and cacheTags from route-cached API routes to the current request.
 *
 * The onRequest interceptor adds a special request header to indicate that
 * this is an internal request originating from Nuxt during SSR.
 *
 * @param bubbleCacheability Which cacheability to bubble. true => everything,
 * route => only route cache, cdn => only CDN headers. Defaults to true.
