Allow fake instances of LibassistantService during unittests

All access to the Libassistant classes is being moved inside
the |LibassistantService| mojom classes, so we need to update
the unittests to fake the |LibassistantService| class, instead
of the Libassistant classes.

This CL introduces a |LibassistantServiceHost| which launches/stops
the Mojom service. This CL also introduces fake objects, and updates
the |AssistantManagerServiceImpl| unittests to use these fakes.

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.

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.
