[Java][Gandiva] Expose Dremio build and tests as new optional container/test

Dremio uses Arrow Java and Gandiva extensively and could provide additional test coverage for the project. We should find a way to expose the downstream build of Dremio as an optional build so major changes can better be evaluated against downstream effects.

@praveenbingo, assigning to you for now but let's figure out who at Dremio can pick this up.

Comece localizando a configuração de build do Arrow Java e do Gandiva, bem como os mecanismos opcionais existentes de contêiner ou teste. Investigue como o build downstream do Dremio poderia ser exposto como um build opcional e defina a conclusão como um caminho opcional de build e teste do Dremio que avalie os efeitos downstream.
