[Merge to M-58] Add a warning for the deprecation of content-initiated data URL navigations
This CL adds a console warning when a page navigates the top level frame to a data URL. The browser tests are added to WebContentsImpl tests to be consistent with the view-source URL tests. This CL also updates most of the layout tests to avoid loading data URLs at the top level. The only exceptions are xss-DENIED-* tests which will be updated when the actual blocking happens.
