[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

Beginne damit, den Windows-Gandiva-Artefakt-Build zu reproduzieren, und untersuche cmake_modules/FindLLVMAlt.cmake und src/gandiva/CMakeLists.txt, wo die gemeldete LLVMAlt-Suche fehlschlägt. Vergleiche die Windows-Konfiguration mit dem vorhandenen Build-Setup. Die Aufgabe ist abgeschlossen, wenn Gandiva-Build-Artefakte unter Windows erfolgreich erzeugt werden können, ohne dass der gemeldete Fehler wegen fehlendem LLVMAlt auftritt.
