c2: add new predefined targetwm_state to match against_NET_WM_STATE in string
New predefined target `wm_state` for rule-based matching. Matchesagainst the cached `_NET_WM_STATE` property of a window in stringrepresentation.NOTE: `wm_state = 'fullscreen'` is not neccessarily identical to`fullscreen`, and `wm_state = 'focused'` is not identical to `focused`.
