[CP-stable] Pub dependencies & widget_preview_scaffold tests relocation (#182317)
Fixes https://github.com/flutter/flutter/issues/182314

This cherry picks in 2 changes to stable
- https://github.com/flutter/flutter/pull/180886
  - The pub roller was busted, and the stable release missed the update
- https://github.com/flutter/flutter/pull/180658
  - Preceded manual pub roll, required to pass analysis with above change.

This is a manual cherry pick, following https://github.com/flutter/flutter/blob/main/docs/releases/Flutter-Cherrypick-Process.md

Around about when we created the release, the pub roller was busted. It is fixed now (https://github.com/flutter/flutter/issues/180503).

Impacted Users: significant
Impact Description: users cannot upgrade to the latest version
Workaround: None
Risk: Not sure, but the pub roll this is cherry picking landed very very close to the stable release being cut. Analysis and flutter doctor all pass.
Test Coverage: For the widget scaffold change, tests are just relocated
Validation steps: https://github.com/dart-lang/test/issues/2570#issue-3684439955

Integration tests

These tests are not hermetic, and use the actual Flutter SDK. While they don't require actual devices, they run flutter_tester to test Dart VM and Flutter integration.

Use this command to run (from the flutter_tools directory):

../../bin/cache/dart-sdk/bin/dart run test test/integration.shard

You need to have downloaded the Dart SDK in your Flutter clone for this to work. Running ../../bin/flutter will automatically download it.

Coverage exclusion

These tests are expensive to run and do not give meaningful coverage information for the flutter tool (since they are black-box tests that run the tool as a subprocess, rather than being unit tests). For this reason, they are in a separate shard when running on continuous integration and are not run when calculating coverage.

Adding new test files

When adding a new test file make sure that it ends with _test.dart, or else it will not be run.
