Ömer Sinan Ağacan 9ed368c2e1 [dart2wasm] Use only JS strings in JSCM
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.
