This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

* removes an extra `)` in `app_bar.dart`
* Moves class definitions and getter definition out of the `main` method
in `widget_state.dart` (defining classes/getters inside of methods is
not allowed in Dart)
The formatter was stumbling over these syntax errors.
Fixes#138270.
Moves the majority of the logic of MaterialStateProperties down to the widgets layer, then has the existing Material classes pull from the widgets versions.
