DDC implementation of experimental dynamic modules.

In particular,

* Provides a DDC implementation for dynamic modules, where the download
  and instantiation of the module is delegated to the embedder of the
  program.

* Exposes an embedding API to allow embedders to define the loading logic.

* Adds a flag to compile code as a dynamic module. This includes
  generating an entrypoint trampoline and checks to validate that a
  dynamic module doesn't stump over previously defined libraries.

* Adds test coverage for DDC under `pkg/dynamic_modules/test/`.

Test suite can be run by executing:
```
DART_CONFIGURATION=ReleaseX64 out/ReleaseX64/dart-sdk/bin/dart \
    pkg/dynamic_modules/test/runner/main.dart -t ddc
```

Once we provide integration of test configuration results to that test
runner, we will add it as part of the test matrix.
