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.

The generated widget_preview_scaffold project needs to explicitly
reference the assets from the parent project's pubspec.yaml. This change
updates flutter widget-preview start to read the parent project's
pubspec.yaml and add references to the assets listed to the
widget_preview_scaffold's pubspec.yaml. If generate: true is set in the
parent project, a reference to the autogenerated flutter_gen package is
manually added to the widget_preview_scaffold's package_config.json.
