[Java][JNI][Windows]: Enable support for Gandiva build artifacts on Windows OS

### Describe the enhancement requested

Enable support for Gandiva build artifacts on Windows OS.

This is the current error message if we try to build Gandiva artifacts on Windows OS environment:

```

### Component(s)

Developer Tools, Java

Commencez par reproduire la compilation des artefacts Gandiva sous Windows et inspectez cmake_modules/FindLLVMAlt.cmake ainsi que src/gandiva/CMakeLists.txt, où la recherche de LLVMAlt signalée échoue. Comparez la configuration Windows avec la configuration de build existante. La tâche est terminée lorsque les artefacts de build Gandiva peuvent être produits avec succès sous Windows sans l’échec signalé dû à l’absence de LLVMAlt.
