Original change's description:
> Window Placement: Implement Screens and ScreenAdvanced interfaces
>
> This CL makes the following changes for a planned API redesign:
> docs.google.com/document/d/1lgCentReLlym6j9kBS_Qo3r2HHZ6Ov7cSGjSWyi8cYs
>
> 1) Add Screens interface to vend multi-screen info for windowing.
> - RuntimeEnabled and permission-gated; designed like window.screen.
>
> 2) Add ScreenAdvanced interface, to extend Screen with extra info.
> - Make Screen impl non-final; override functions in ScreenAdvanced.
>
> 3) Add WindowScreens supplement, to host Window.getScreens().
> - Rename the previous API access point to getScreensDeprecated().
>
> 4) Add ScreenInfo::is_primary & is_internal to expose in ScreenAdvanced.
> - Add ScreenInfo::display_id for internal logic, it is not web-exposed.
>
> 5) Propagate multi-screen VisualProperties from browser to renderers:
> - Replace the singular ScreenInfo member with a new ScreenInfos struct.
> - Encapsulates multi-screen information and a current screen id.
> - Add [mutable_]current() for easy/legacy access to the current screen.
> - Validate mojo struct traits in [de]serialization; add tests.
>
> 6) Update WidgetBase, ChromeClient, tests, and more code accordingly.
> - Update RenderWidgetHostViewMac's cached display::Display on changes.
> - Add CoreInitializer plumbing to fire Screens.change in modules/.
>
> FOLLOWUP: Refine Screens::ScreenInfosChanged implementation.
> FOLLOWUP: Propagate multi-screen info to RemoteFrames.
> FOLLOWUP: Update/add tests; remove old API and plumbing.
> FOLLOWUP: Add WindowScreens PermissionObserver & set_disconnect_handler?
> FOLLOWUP: Use WebContentsImpl's NativeView in RWHI::GetScreenInfo?
