Create chrome/browser/api directory. Move infobar delegates used by Autofill to the directory.

Also, consolidate infobar delegate interfaces under infobars/ rather than some under infobars/ and some under tab_contents/, as the ones under tab_contents/ were not coupled with tab_contents/ in any way.

Remove feedback/proto/extension.pb.h from Autofill's DEPS file simply by dropping the include, it was not being used.
