Send SameSite=Lax cookies for FedCM requests

These are cross-site requests, so cookies would not normally be
sent, and a couple of these requests are also POST requests,
so it is not possible to configure the request in a way to
send these cookies from the client's side.

See this discussion for background:
https://github.com/w3c-fedid/FedCM/issues/587

See also discussion in net-dev:
https://groups.google.com/a/chromium.org/g/net-dev/c/-TIHQd-7-oM/m/0NmLBzgvAQAJ

This is behind a flag for now.

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.
