Lookalikes: Add a console message for Combo Squatting heuristic

Chrome prints a console message when a domain is flagged with any of the
lookalike heuristics to allow site owners to find the appeals links. For
new heuristics, before fully launching them, the message has an extra
line explaining the future behavior of Chrome.

This CL prints a console message for domains that are flagged by the new
Combo Squatting heuristic. The message will be removed from the console
once the heuristic is fully launched in future Chrome versions.
Additionally, the code for printing lookalike console messages is
refactored to increase readability and usability.

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.
