Matan Lurey 42daa3bb56 Add a minimal example of using package:test. (flutter/engine#51726) ...

Work towards https://github.com/flutter/flutter/issues/133569.

This PR is a proof of concept that shows we're able to use `package:test` in `flutter/engine` instead of `package:litetest`.

I think it also shows that, if we're going to continue to vend dependencies this way, we might want to re-think our strategy in terms of using `pub` as a management tool - it's quite unwieldy already. For example, here is every `pubspec.yaml` file in the repo:

```sh
$ find . -name 'pubspec.yaml' -exec sh -c 'echo "$0 $(wc -l < "$0")"' {} \;

I'll file a follow-up issue to discuss pub-package management in the engine.
