Refactor educational tips to work with merged ranking

We need more clean up in educational tips code base to remove the
Tip enum and use a single enum. This will be done in follow ups.

- Make each tip a different module so its cleaner to handle ranking
  logic in one place.
- Enable support for showing multiple ephemeral cards in ntp.
- Deprecate EDUCATIONAL_TIP module type. And Fix the logic related to
  iterating enums incrementally, added utility to fetch active modules.
- Remove special case handling of EDUCATIONAL_TIP module in magic stack
  code base, only the ranker deals with the complexity for ephemeral
  modules.
- Move the logic to notify card being shown and card clicked into home
  delegate and the home mediator sends these to native.
  onModuleClicked() and onModuleBuilt() already existed.

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.
