[Feature] cdc_vcom.c里面的product string以及manu string如何修改？

[FlyyingPiggy2020]

Describe problem solved by the proposed feature

我想修改usb cdc设备中的MANUFACTURER_STRING和PRODUCT_STRING
这部分源代码如下：

const static char* _ustring[] =
{
    "Language",
    "RT-Thread Team.",
    "RTT Virtual Serial",
    serno,
    "Configuration",
    "Interface",
};

我是直接通过修改_ustring这个数组去修改吗？那样子不就动了sdk里面的代码了？

Describe your preferred solution

提供一个宏定义类似：

    const static char *_ustring[] = {
        "Language",
        VCOM_MANUFACTURER_STRING,
        VCOM_PRODUCT_STRING,
        serno,
        "Configuration",
        "Interface",
    };

在KConfig去配置：

                if RT_USB_DEVICE_CDC
                    config RT_VCOM_TASK_STK_SIZE
                        int "virtual com thread stack size"
                        default 512
                    config RT_CDC_RX_BUFSIZE
                        int "virtual com rx buffer size"
                        default 1024
                    config RT_VCOM_MANUFACTURER_STRING
                        string "virtual com manufacturer string (max 32 ASCII chars)"
                        default "RT-Thread Team."
                    config RT_VCOM_PRODUCT_STRING
                        string "virtual com product string (max 32 ASCII chars)"
                        default "RTT Virtual Serial"
                    config RT_VCOM_TX_USE_DMA
                        bool "Enable to use dma for vcom tx"
                        default n
                    config RT_VCOM_SERNO
                        string "serial number of virtual com"
                        default "32021919830108"
                    config RT_VCOM_SER_LEN
                        int "serial number length of virtual com"
                        default 14
                    config RT_VCOM_TX_TIMEOUT
                        int "tx timeout(ticks) of virtual com"
                        default 1000
                endif
