C++23 suggests us `#elifdef` and `#elifndef` as a new way to write directives in a long conditional preprocessing block.
Needs a check that will find usages of `#elif` followed by `defined identifier`(or `!defined identifier`) and will suggest to change it to `#elifdef identifier`(or `#elifndef identifier`).
BEFORE:
```
#ifdef CPU
std::cout << "4: no1\n";
#elif defined GPU
std::cout << "4: no2\n";
#elif !defined RAM
std::cout << "4: yes\n";
#endif
```
AFTER:
```
#ifdef CPU
std::cout << "4: no1\n";
#elifdef GPU
std::cout << "4: no2\n";
#elifndef RAM
std::cout << "4: yes\n";
#endif
```
