This change removes support for external strings from the VM along with Dart_NewExternalLatin1String, Dart_NewExternalUTF16String and Dart_IsExternalString Dart C API functions. External strings are not used by the VM nor any known embedder, but Dart VM was paying the maintenance and performance price for the external string implementation classes.
