Fixes#119401
This PR is to:
* add `Card.filled` and `Card.outlined` factory methods so that we can use tokens for these two types of cards to generate default theme instead of providing hard-corded values in example.
* update card.2.dart example.
* add test file for card.2.dart example.
* fix some mismatch caused by editing the auto-generated defaults by hand in navigation_bar.dart and navigation_drawer.dart.
* Added support for surfaceTintColor and shadowColor to the Dialog widgets.
* Updated the defaults for Material.shadowColor and Material.surfaceTint to allow turning off the features with a transparent color.
* Added support for shadowColor and surfaceTintColor for Drawer widget.
