Integrate material color theming support within DevTools

[jacob314]

It could make sense to embed some functionality from material-color-utilities in Flutter DevTools in a future Theme tab.

Closing as stale. Embedding a Material color utilities / Theme editor tab is out of scope for core DevTools, which focuses on core diagnostic, performance, memory, and debugging tools. Domain-specific and package tooling is now supported via DevTools Extensions, which would be the recommended path if the community or Material team wants to build a dedicated theme management extension.

If there is more work to do here, please let us know by filing a new issue with up to date information. Thanks!
