type-c-service: Remove interior mutability from service

[RobertZ2011]

• Hook-up power policy events again
• Remove interior mutability from service and move event receivers to a separate struct.

Pull request overview

Refactors the host↔EC communication path (notably eSPI) toward a direct async “relay” model, and decouples several services’ wire/message types into dedicated *-messages crates to improve composability and testability.

Changes:

• Introduces a generic MCTP relay framework (embedded-service::relay) and updates eSPI service to use it.
• Splits debug/battery message types into new debug-service-messages / battery-service-messages crates and updates services accordingly.
• Updates examples/workspace/CI to account for new crates, features, and adds coverage reporting in GitHub Actions.
