Example/Test - Use the new CefRedist32CopyResources/CefRedist64CopyResources targets

On Nuget restore the CefRedist32/CefRedist64 properties aren't accessible until after the project has been closed
and reopened. (Think clean checkout where the packages folder doesn't exist).
The Targets behave different and can be called, so this works around the problem.
