boring_to_beautiful: Inline adaptive packages (#2321)

Fixes flutter/flutter#170021 by inlining
discontinued `adaptive` packages.

## Pre-launch Checklist

- [x] I read the [Effective Dart: Style] _recently_, and have followed
its advice.
- [x] I signed the [CLA].
- [x] I updated/added relevant documentation (doc comments with `///`).
- [x] All existing and new tests are passing.

If you need help, consider asking for advice on the #hackers-devrel
channel on [Discord].
