Move resolve-url-loader into Next.js (#32932)
* Move resolve-url-loader into Next.js

Fixes #32157

Moves resolve-url-loader into Next.js and strips out all features that are not used like `rework` support. Will reduce install size as well as allow for optimizing the approach in the near future.

* Update precompiled

* Use loader-utils 2

* Update trace test

* Revert "Update trace test"

This reverts commit 7c09a07871cc0ab72d5fcd4151a2d8efbc1aad8f.

* Add es5-ext as it's used in trace tests

* Update join-function.js

* Update bundle5.js
