ash/display: Report displays to Display Popularity

1. The displays info is saved after a mode change.
2. When we store the current display prefs, the
   displays are then reported.
3. External displays that haven't been reported before are the one that
   get added to the structured metrics.
4. "Seen" displays are saved to the local prefs, to avoid reporting them
   again.

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.
