[dart2wasm] Dart format pkg/wasm_builder

The change in [0] increased the language version of pkg/dart2wasm. That
in return changes how the package is formatted by the autoformatter.

This CL runs now the formatter to re-format the code. Unfortunately this
makes blame lists worse. But not doing it will make us have to disable
auto-formatting before saving files which is very annoying.
