feat(ble): 添加 Swift Pair 模块支持

- 在 CMakeLists.txt 中添加 swift_pair_module.c 源文件
- 将 BLINKY_BLE_BOND_MULTI 配置项重命名为 BLINKY_BLE_BOND_MULTI_INTERNAL 并移除帮助文本
- 在 prj.conf 中启用 CONFIG_BT_ADV_PROV_SWIFT_PAIR 配置选项
- 新增 swift_pair_module.c 实现 Swift Pair 功能，包括：
  - 监听蓝牙配对多设备事件和蓝牙对等操作事件
  - 根据选中的身份标识控制 Swift Pair 载荷的启用/禁用
  - 当设备被选中或擦除时更新 Swift Pair 状态
