Revert "Fix modulepreload to send proper referrer headers"

This reverts commit 33458870989e18fbc949b5c538fcaa60daa2f7f1.

Reason for revert: it landed accidentally before feature approval!!
Bug: 409959472

Original change's description:
> Fix modulepreload to send proper referrer headers
>
> Modulepreload requests were using NoReferrer() instead of
> ClientReferrerString(). This change ensures modulepreload sends the
> client's referrer, consistent with the HTML specification which requires
> using the client's referrer for module fetches.
>
> Added a test that verifies both dynamic imports and modulepreload
> correctly send referrer headers. Used an onload event rather than
> a timeout for better test reliability.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
