Adds static errors in web backends requiring external members to be annotated with @JS(). Members can be annotated directly, or on the enclosing class or library. Also removes duplicate checks in dart2js for non-native external members that are now covered by the checks on external @JS members.

FE/analyzer shared code
This package contains logic that is shared between the front_end and analyzer packages. It is intended solely to facilitate development of the Dart SDK, and is not intended for use by end users. In particular, this package has no public API, so no guarantee is made of compatibility between one version of the package and the next.
End users should consider using the analyzer package to analyze Dart source code.
