Meanwhile, `WPE_DRM_DEVICE` is just checked lazily in `wpe_display_get_drm_device`, before asking the child class for the drm device. In fact, IIUC, currently, if we use `WPE_DRM_DEVICE, we can have the scenario where `WPEDisplayWayland` might be using a given `WPEDRMDevice` (its `priv->drmDevice`) that's different from the one returned by `wpe_display_get_drm_device`, which would be `WPEDisplay`'s `priv->overridenDRMDevice`.
