Introduce tone-based surfaces and accent color add-ons - Part 2 (#138521) 
This PR is to introduce 19 new color roles and deprecate 3 color roles in `ColorScheme`.
**Tone-based surface colors** (7 colors): 
* surfaceBright
* surfaceDim
* surfaceContainer
* surfaceContainerLowest
* surfaceContainerLow
* surfaceContainerHigh
* surfaceContainerHighest

**Accent color add-ons** (12 colors):
* primary/secondary/tertiary-Fixed
* primary/secondary/tertiary-FixedDim
* onPrimary/onSecondary/onTertiary-Fixed
* onPrimary/onSecondary/onTertiary-FixedVariant

**Deprecated colors**:
* background -> replaced with surface
* onBackground -> replaced with onSurface
* surfaceVariant -> replaced with surfaceContainerHighest

Fix token usages on Regular Chip and Action Chip (#141701) 
The regular chip and the action chip templates were referencing non existent M3 design tokens.

Fixes https://github.com/flutter/flutter/issues/141288

The `ActionChip` doesn't have any visual difference. Even though the template and file changes, the default `labelStyle` color already uses `onSurface`.
For the reviewer, I've changed the `action_chip_test` to expect a color from the colorScheme so that it is more explicit that the color might not be the same as the labelLarge default in the global textTheme, even if for this case the color is the same.

The regular `Chip` does have visual differences, in particular, the label and trailing icon colors, which were not following the specification. In order to fix this, the regular chip now is based from the `filter-chip` spec as described in the linked issue.

Add Card.filled and Card.outlined factory methods (#136229) 
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.

Add support for M3 motion (#129942) 
## Description

This adds support for M3 easing and duration tokens.

This PR includes these changes:
* Generation of duration and easing constants, in `Durations` and
`Easing`, respectively (`Curves` is already taken in the `animation`
library)
* Add 3 Dart fixes

Once this is merged, I'll migrate packages/plugins/customers and then

Fix Material 3 Scrollable TabBar (#125974) 
fix https://github.com/flutter/flutter/issues/117722

### Description
1. Fix the divider doesn't stretch to take all the available width in the scrollable tab bar in M3
2. Add `dividerHeight` property.
3. Update the default tab alignment for the scrollable tab bar to match the specs (this is backward compatible for M2 with the new `tabAlignment` property).

### Bug (default tab alignment)

# Description
M3 ListTile couldn't be customized using `ColorScheme` colors. 

- This PR updates the list tile text defaults to `ColorScheme` text color tokens.
- Improved the `ListTile` template to use the token group.
- Update docs and tests.

```dart
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.red).copyWith(
          onSurface: Colors.yellow,
          onSurfaceVariant: Colors.green,
        ),

Improve defaults generation with logging, stats, and token validation (#128244) 
## 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

## Related Issues
 - Fixes https://github.com/flutter/flutter/issues/122602

## Tests
 - Added tests for `TokenLogger`
 - Regenerated tokens, no-op except version removal

## Future work
A future PR should replace or remove the following invalid tokens usages
