fixes https://github.com/flutter/flutter/issues/115827
fixes https://github.com/flutter/flutter/issues/101325

### Description
1. This PR adds a new MaterialState `color` property to all the chips (this makes it possible to customize chips in all states from the M3 specs).
2. Updated defaults to use the new  MaterialState `color` property.
3. Updated and added new tests to all the chip test classes.
