[Ad Tracker] Add tests to demonstrate unexpected behavior in redirect scenarios

Problem: When a redirecting script is about to execute,
`AdTracker::WillExecuteScript` gets only the *initial* URL. The tagging
and ancestor linking decision is based on this URL, leading to
unexpected behavior (e.g., If a script's initial URL is not on
filterlist, but it redirects to a URL that is, its subsequently
created frames/scripts are not tagged as ads).

This CL adds tests to demonstrate the current behavior, and adds
comments to make it clear that this is unwanted and should be fixed.

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.
