Merge revised Instrumentation framework into the Polyglot API
- Required language implementation support now in TruffleLanguage
- Instrumentation services provided by the new Instrumenter class
- Reduced public API exposure; communication with other components via Accessor
- Several methods removed from the Node class
- Many test rewritten or using a new "test mode" because of limited access to Engine services
Merge with c66f520ad8562b906a878e9b3293aaf54270db90
