type-c-service: Thread UCSI port commands to hardware

[RobertZ2011]

Breaking change due to the new trait function.

Depends on:

• ucsi/lpm: Add iterator over GET_PDOS content embedded-usb-pd#51
• asynchronous/embassy: Add UCSI workarounds tps6699x#75

Pull Request Overview

This PR implements threading of UCSI (USB Type-C Connector System Software Interface) port commands to the hardware controller, enabling proper command routing and response handling for UCSI operations.

• Adds support for executing UCSI commands through the controller interface
• Updates the UCSI service to route commands to hardware instead of returning mock responses
• Implements command execution in both TPS6699x driver and mock controller
