For development to continue on systems (such as optimus laptops) that have multiple GPUs, we need a way to reference all of the renderers that have been created for devices in the system. A wlr_multi_gpu struct holds renderers coming from two different sources: 1. the primary renderer (given to us by the compositor) 2. drm sub backends, each of which has a renderer created for cross-GPU copies. This change provides a way to access all of these from the same place.
