feat(usb_cdc): 添加USB CDC ACM控制台和日志后端支持

添加zephyr,console和zephyr,log-uart设备树配置，启用UART控制台和日志功能，
同时增加第二个CDC ACM UART实例用于控制台输出。在prj.conf中启用相关配置项。

refactor(protocol): 优化协议会话状态管理并增强日志记录

引入proto_session_set函数统一管理协议会话状态转换，添加详细的日志输出来跟踪
状态变化、消息处理和传输事件，提高系统的可调试性。

feat(usb_device): 增强USB设备模块状态跟踪和日志输出

为USB栈、总线和公共状态添加命名函数，实现详细的状态转换日志记录，包括USB
连接、断开、使能等关键事件的日志输出，便于系统调试和问题排查。
