Add functionality for a TFLite performance experiment.

This change enables experimenting with executing TFLite models during
normal browser operation. The experiment's goal is to measure the
performance of machine learning models using TFLite and Chrome's ML
service. This will also enable us to measure any potential impact on
the browser behavior when executing more sophisticated
ML models, such as Language Identification and Translation, on-device.

This creates a Keyed Service that handles construction of the TFLite
model that navigations can query. This change also creates a
WebContents Observer to allow experimenting with executing the model
at various events during browser use, including navigation start,
commit and load. This events will be added in later changes.

This change also includes logging functionality so the necessary
model execution metrics can be recording during local testing.

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.
