Initial Aura/Ozone support.

It is possible to build and run cefsimple using this change
on the top of test ozone plugin.

Main changes:

 * Building CEF3 using Aura.
 * Added support for external GYP configuration script in cef_create_projects.sh
   to allow architecture specific configurations.
 * Added new Aura based browser host implementation.
 * Made dependency on Chromium Toolkit Views optional, since the core Ozone
   plugins can't support toolkit views.
 * Added new Aura Platform Data class to interface Aura Windows.
