fix(serial_v2): tx_fifo->rb.buffer_ptr not init when RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING 
为什么提交这份PR (why to submit this PR)
serial_v2驱动框架，rt_serial_tx_enable()函数，在 DMA阻塞发送(RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING) 的时候，使用rt_malloc分配了tx_fifo内存，但是并未对tx_fifo->rb.buffer_ptr指针进行初始化（rt_malloc不会自动初始化内存），因此可能导致buffer_ptr是一个随机指针。但是rt_serail_write()函数需要根据tx_fifo->rb.buffer_ptr是否为RT_NULL来判断是调用_serial_fifo_tx_blocking_nbuf()还是_serial_fifo_tx_blocking_buf()。

由于tx_fifo->rb.buffer_ptr可能是一个随机值（不一定为RT_NULL=0），导致RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING模式下调用了_serial_fifo_tx_blocking_buf()，但是rb没有真正开辟内存空间，导致内存异常

你的解决方案是什么 (what is your solution)
rt_serial_tx_enable()，在DMA阻塞发送分支下，对tx_fifo->rb.buffer_ptr进行初始化，赋值为RT_NULL。

USB CDC驱动在win11下无法识别，看了微软的描述修改子类后正常 (#6783) 
这是微软关于此问题的链接:
 https://learn.microsoft.com/zh-cn/windows-hardware/drivers/usbcon/usb-driver-installation-based-on-compatible-ids#usbsersys-installation
Windows 10 及更高版本
从 Windows 10 开始，Usbser.inf 已添加到 %Systemroot%\INF 目录，该目录加载 Usbser.sys 作为设备堆栈中功能设备对象 (FDO) 。 如果设备属于通信和 CDC 控制设备类， Usbser.sys 加载。 无需编写自己的 INF 来引用驱动程序。 驱动程序是基于与包含在 Windows 中的其他 USB 设备类驱动程序相似的兼容 ID 匹配来加载的。

USB\Class_02

USB\Class_02&SubClass_02

如果要自动 加载Usbser.sys， 在设备描述符中将类代码设置为 02，将子类代码 设置为 02。 有关详细信息，请参阅 USB 通信设备类。 使用此方法时，无需为设备分发 INF 文件，因为系统使用的是 Usbser.inf。
如果设备指定类代码 02，但子类代码值不是 02，则 Usbser.sys不会自动加载 。 即插即用管理器尝试查找驱动程序。 如果找不到合适的驱动程序，则设备可能未加载驱动程序。 在这种情况下，你可能需要加载自己的驱动程序或编写引用另一个内置驱动程序的 INF。

Grissiom 981d929b56 ringbuffer: fix the ambiguous name 
RT_RINGBUFFER_SIZE could mean "the size of the whole buffer", "the size
of the empty space" or "the size of the data". Moreover, it's never a
micro anymore. Change it to rt_ringbuffer_data_len before it's too late.
Also, RT_RINGBUFFER_EMPTY is changed to rt_ringbuffer_space_len.
