Dev, examples/api, etc updated for Material 3 by default (#129683)

Updated tests in dev, examples/api, and tests/widgets to ensure that they continue to pass when the default for `ThemeData.useMaterial3` is changed to true. This is the final set of changes required for https://github.com/flutter/flutter/issues/127064.
