feat(ch934x): 添加GPIO方向控制和串口参数配置功能
- 添加Ch934xMode和GpioDirection枚举类定义 - 实现GPIO方向控制相关方法(setGpioDir/queryGpioDirFromCache) - 添加GPIO使能控制(enableGpio)和数量/组数查询(getGpiocount/getGpiogroup) - 实现串口参数配置(setSerialParameter)包括波特率/数据位/停止位/校验位/流控 - 添加Break信号控制(setBreak)功能 - 实现当前串口模式查询(getCurrentMode) - 添加设备连接状态查询(isConnected)和已打开设备列表获取(getConnectedDevices) - 更新文档说明GPIO方向控制和串口参数配置用法 - 在示例应用中添加相关功能按钮和操作逻辑
