refactor: use Parcelable Bundle for state management

- 在 ScrcpyOptions 中引入 Parcelable 数据类 `Bundle`，用于封装各项配置
- 更新了使用新 Bundle 结构读写配置的方法
- 使用 StateFlow 增强状态管理，实现响应式 UI 更新
- 重构 toClientOptions 方法，接受 Bundle 参数以提高清晰度和可维护性
- 调整音频和视频编解码器设置，使其使用新的 Bundle 结构
- 更新 ConfigPanel 以反映 ScrcpyOptions 的变化，并更有效地管理状态
- 移除 DeviceWidgets 中的未使用代码并清理导入
- 重构解码流程，驻留一个中转 Surface，解决先前 Surface 销毁后解码无法恢复的问题
