winex11.drv: Track external changes to _NET_WM_STATE in net_wm_state. 

In some cases, WM's will modify the _NET_WM_STATE of our own windows.
Most notably, this can happen when the WM maximizes our window, but
mutter has been known to alter the fullscreen state as well. If we
want to reconfigure our window later, we'll probably have to remove
these states, which means we need to remember that they were set.
