feat(usb_hid_keyboard): 支持键盘LED报告处理

- 添加KBD_LED_REPORT_WITH_ID_SIZE宏定义以支持带ID的LED报告
- 实现keyboard_handle_led_report函数来处理不同长度的LED报告
- 在keyboard_set_report中添加对HID_REPORT_TYPE_OUTPUT类型的支持
- 优化keyboard_output_report函数以复用LED报告处理逻辑
- 移除datetime_event中的INIT_LOG_ENABLE标志

支持处理长度为1字节或2字节（包含report ID）的键盘LED报告，
并提供适当的错误日志记录功能。
