Now that we have a CRTC list in the DRM-backend, we can iterate through it and look for the CRTCs that do not have assigned outputs in order to find unused CRTCS. So we can drop unused_crtcs from struct drm_backend and also drop the functions drm_backend_update_unused_outputs() and wl_array_remove_uint32().
