Original issue's description:
> Remote assistance on Chrome OS Part VII - Clipboard Injection
>
> On Chrome OS, the clipboard is managed by aura instead of the underlying
> native platform (e.g. x11, ozone, etc).
>
> This CL introduces a class that
> 1) Monitors the aura clipboard on the host for changes and notifies the client clipboard.
> 2) Provides an interface to inject clipboard event into aura.
>
> The public API of this class can be called in any thread as internally it
> always posts the call to the |ui_task_runner|.  On ChromeOS, that should
> be the UI thread of the browser process.
