Send test message channel from the test frame (#131881)
Towards https://github.com/dart-lang/test/issues/2065

The flutter test runner uses the copy of `host.dart.js` from the copy of
`package:test` that surfaces in the pub solve for `flutter_tool`. This
copy has been updated to allow either the old pattern of communication,
or this new pattern. The new pattern removes an extra hop and use of the
frame `window.onMessage` messages.
