headless-browser: Implement a stubbed clipboard API

Browse source 
We currently rely on UI-specific APIs to interact with the system
clipboard from AppKit and Qt. We do not have access to these from
headless-browser.

We should ultimately implement these APIs without relying on the UI as
a middle-man. For now, store a clipboard item so that we may exercise
the clipboard WPT tests.
