WebUI: Add a dummy Polymer3 WebUI demo page for experimentation. 

This page is "parked" temporarily under chrome://print/polymer3/demo.html,
and only included for optimize_webui=false, to avoid the overhead of
adding a new top-level WebUI page, and should be removed once
experimentation concludes.
