版本控制规范：https://semver.org/
目前的版本子号不是很规范，其中RT_VERSION甚至和VS那边造成了冲突
```c
/* RT-Thread version information */
#define RT_VERSION 4L /**< major version number */
#define RT_SUBVERSION 1L /**< minor version number */
#define RT_REVISION 1L /**< revise version number */
```
参考ESP32：
```c
/** Major version number (X.x.x) */
#define ESP_ARDUINO_VERSION_MAJOR 2
/** Minor version number (x.X.x) */
#define ESP_ARDUINO_VERSION_MINOR 0
/** Patch version number (x.x.X) */
#define ESP_ARDUINO_VERSION_PATCH 3
```
建议改成：
```c
/* Major version number (X.x.x) */
#define RT_VERSION_MAJOR 4
/* Minor version number (x.X.x) */
#define RT_VERSION_MINOR 2
/* Patch version number (x.x.X) */
#define RT_VERSION_PATCH 0
```
