[libvirt] [RFC PATCH 3/7] conf: Introduce virDomainDefHasSpiceGL helper

This helper will later help us to make corresponding changes when building QEMU cmdline, depending on what implementation of vfio-pci display should be used - dmabuf (requires OpenGL) vs vfio region mapping (doesn't need OpenGL).
