Move check for sky cubemap array back into the SkyRD initializer so it is set before being used.

Previously it was moved out of this function becuase we relied on RenderingServer::get_video_adapter_name which wasn't available yet.

However, that was unnecessary since it is just a wrapper around RenderingDevice::get_device_name() which is available.
