[native_assets_cli] Separate out public API (#885)

This does not change any of the public API yet, but it slims down the API surface of `package:native_assets_cli` to the bare minimum.

Internal details may be accessed in `package:native_assets_builder` via:

```dart
import 'package:native_assets_cli/native_assets_cli_internal.dart';
```

This enables the yaml serialization/deserialization to live in one place and be unit tested as one.

One hack is that we also access `package:native_assets_cli/native_assets_cli_internal.dart` in `package:native_toolchain_c` in the unit tests to depend on the C compilers provided on the Dart CI.
