255cc9b9 - Replace `Promise.withResolvers` polyfill with `DetachedPromise` (#56954)

Replace `Promise.withResolvers` polyfill with `DetachedPromise` (#56954) In an attempt to avoid introducing experimental features into the Next.js userland space, we're reverting the `Promise.withResolvers` polyfill and preferring an internal `DetachedPromise` interface.
