Add OPENEULER_VERSION_CODE to version.h, so modules or applications can identify the specific kernel version.
In most cases, the out-of-tree module needs to identify the release version of the openEuler for interface adaptation. The existing OPENEULER_VERSION() and OPENEULER_VERSION_CODE() cannot distinguish between LTS versions and innovative versions. Therefore, a new macro OPENEULER_LTS is introduced.
The version information is generated in "linux/version.h", as bellow: include/generated/uapi/linux/version.h
``` #define OPENEULER_LTS 0 // 1: LTS; 0: none LTS #define OPENEULER_MAJOR 9999 // OS Major version, 9999: none released #define OPENEULER_MINOR 0 // SP release version #define OPENEULER_VERSION(a,b) (((a) << 8) + (b)) #define OPENEULER_VERSION_CODE 2559744 ```
