为什么提交这份PR (why to submit this PR)

stm32/stm32f103-blue-pill中存在编译错误（#10594）
经测试，发现STM32的大多数型号都存在该问题。

你的解决方案是什么 (what is your solution)

我尝试复现该issue，但只发生了前3个报错。（或许还需要更多细节？）
解决方法是在bsp\stm32\stm32xxx\board\Kconfig中，添加V2缓冲区相关配置。

请提供验证的bsp和config (provide the config and bsp)

按照 #10600 中的建议进行了重新修改

[dongly]

还要生成 rtconfig.h

[wdfk-prog]

LGTM

[wanwandegit]

问题似乎不止在stm32f103-blue-pill中存在，我再进一步改一下

[wanwandegit]

STM32中的大多数型号都存在该问题，在提交中一并修改了。
前一次提交修改了Kconfig中的原有默认值，现在也改回去了。

[wanwandegit]

修改行数好像有点多了，可能需要说明一下。
以UART1为例，具体是将bsp\stm32\stm32xxx\board\Kconfig中config BSP_USING_UART1及之后的内容替换为如下内容（增加导致报错的宏定义以及其他V2缓冲区相关配置）：

menuconfig BSP_USING_UART1
                bool "Enable UART1"
                default n  #这里以原默认值为准
                if BSP_USING_UART1
                    config BSP_UART1_RX_USING_DMA
                        bool "Enable UART1 RX DMA"
                        depends on BSP_USING_UART1 && RT_SERIAL_USING_DMA
                        default n

                    config BSP_UART1_TX_USING_DMA
                        bool "Enable UART1 TX DMA"
                        depends on BSP_USING_UART1 && RT_SERIAL_USING_DMA
                        default n

                    config BSP_UART1_RX_BUFSIZE
                        int "Set UART1 RX buffer size"
                        range 64 65535
                        depends on RT_USING_SERIAL_V2
                        default 256

                    config BSP_UART1_TX_BUFSIZE
                        int "Set UART1 TX buffer size"
                        range 0 65535
                        depends on RT_USING_SERIAL_V2
                        default 256

                    config BSP_UART1_DMA_PING_BUFSIZE
                        int "Set UART1 RX DMA ping-pong buffer size"
                        range 32 65535
                        depends on RT_USING_SERIAL_V2 && BSP_UART1_RX_USING_DMA
                        default 64    
                endif

因为存在该问题的型号比较多，所以行数看起来很多，实际上只是做了一些替换。

[wanwandegit]

根据bsp\stm32\stm32f407-rt-spark\board\Kconfig, bsp\stm32\stm32h750-artpi\board\Kconfig, bsp\stm32\stm32h7r7-artpi2\board\Kconfig等文件的内容，TX缓冲区的默认值设为0更加合适。（缓冲区大小和Kconfig中添加的部分也参考自这些文件）

导致 #10594 中错误的原因应该也在于：bsp\stm32\libraries\HAL_Drivers\drivers\drv_usart_v2.c在近期添加了serial_v2相关代码，但配置文件没有及时更新。
