[ Widget Preview ] Add support for theme and brightness properties on Preview (#167001)
The `theme` parameter of `Preview(...)` allows for developers to provide
a callback that returns a `PreviewThemeData` instance which can contain
theming data for Material and Cupertino widgets in both light and dark
modes. The provided theme data will be injected into the widget tree and
applied to the previewed widget.

The `brightness` parameter allows for developers to specify an initial
brightness setting (e.g., light vs dark mode) for the previewed widget.
If not provided, the current system default is used.

A new button has also been added to each widget preview card that allows
for toggling between light and dark mode for individual previews.

Automated Flutter integration test suites

Each suite consists of either a complete Flutter app and a flutter_driver specification that drives tests from the UI, or a native app that is meant to integrate with Flutter for testing.

Intended for use with devicelab tests.

If you want to run a driver test locally, to debug a problem with a test, you can use this command from the appropriate subdirectory:

flutter drive -t <test> --driver <driver>

For example:

flutter drive -t lib/keyboard_resize.dart --driver test_driver/keyboard_resize_test.dart

New tests require new CI runner

Adding code to this directory will not automatically cause it to be run by any already existing ci tooling. This directory is intentinally a "choose your own adventure" piece of tooling.
