Refactor libraries so that JSCM will only use `JSStringImpl` class for strings. The goal is to disentangle the native string classes and `JSStringImpl` and start testing `JSStringImpl` in isolation. Changes: - `dart:_string` is no longer available in JSCM. - Make `int.toString` external to allow patching it differently in JSCM and normal modes. `toString` implementations are in `boxed_int_to_string.dart` patch files. - `int.parse` now uses JS `parseInt`. However `parseInt` is not compatible with Dart's `int.parse` so this will cause some more test failures in JSCM for now. - Any dependencies to `dart:_string` from JSCM `dart:convert` are removed. The library implementation now uses JS `TextDecoder` for UTF-8 decoding. Note: `TextDecoder` is not available on d8, so text decoding tests will fail on d8. JSON encoding and decoding in `dart:convert` will be updated in a follow-up CL. - Compiler (translator, constant generator, code generator etc.) is updated to allocate the `JSStringImpl`s in JSCM. Initially this will make some JSCM test fail as `int` parsing is not quite right, those will be fixed in follow-up CLs.
