[120] Tag subframe navs for ad third party cookie deprecation access metrics

https://chromium-review.googlesource.com/c/chromium/src/+/4983468
tagged all subresource cookie accesses with a bit indicating whether
the request was used for advertising purposes.

Subframe navigations resources do not use the blink side loading
infra, so they need to be tagged in the browser process to get
coverage.

In order to properly tag the initial ResourceRequest for the
navigation, we need to also turn off an optimization that parallelizes
the first LoadPolicy calculation and navigation start in dry run
mode. This is kept behind a feature flag.

The existing nav handle API,
GetNavigationInitiatorActivationAndAdStatus(), is not sufficient
as we need to include signals outside of the initiator, and currently
the ad status is only propagated with user activation in this signal.

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.
