backend/drm: introduce wlr_drm_connector_state Previously, we were copying wlr_output_state on the stack and patching it up to be guaranteed to have a proper drmModeModeInfo stored in it (and not a custom mode). Also, we had a bunch of helpers deriving DRM-specific information from the generic wlr_output_state. Copying the wlr_output_state worked fine so far, but with output layers we'll be getting a wl_list in there. An empty wl_list stores two pointers to itself, copying it on the stack blindly results in infinite loops in wl_list_for_each. To fix this, rework our DRM backend to stop copying wlr_output_state, instead add a new struct wlr_drm_connector_state which holds both the wlr_output_state and additional DRM-specific information.
