Add abusive notification interaction UKM

Since the "Always allow" and "undo always allow" actions are being used
to evaluate the success of the manual revocation feature, this CL starts
by logging these actions. See the UKM collection section of
go/show-sb-notification-revocations-safety-hub for details. In follow up
CLs, we will log any other actions that are of interest.

See "Privacy considerations" in
go/show-sb-notification-revocations-safety-hub for privacy approval

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.
