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.
## Description
This improves defaults generation with logging, stats, and token validation.
This PR includes these changes:
* introduce `TokenLogger`, with a verbose mode
* prints versions and tokens usage to the console
* outputs `generated/used_tokens.csv`, a list of all used tokens, for use by Google
* find token files in `data` automatically
* hide tokens `Map`
* tokens can be obtained using existing resolvers (e.g. `color`, `shape`), or directly through `getToken`.
* tokens can be checked for existence with `tokenAvailable`
* remove version from template, since the tokens are aggregated and multiple versions are possible (as is the case currently), it does not make sense to attribute a single version
* improve documentation
