feat: 添加HID流控制模块和相关事件处理

- 添加hid_flowctrl_module.c实现HID报告流控制功能，包括FIFO队列管理和
  报告发送控制
- 新增hid_report_sent_event、hid_transport_state_event和
  hid_tx_report_event事件类型及其对应的头文件和实现
- 在CMakeLists.txt中注册新模块和事件源文件
- 修改keyboard_core_module.c以支持队列策略，并添加编码器事件处理逻辑
- 更新usb_hid_module.c将直接的键盘HID报告事件改为通过
  hid_tx_report_event进行传输，并添加状态报告事件
- 在keyboard_hid_report_event中增加queue_policy字段以支持不同
  队列策略
