wayland: Keep wl_shell_surface state during loss of window

Browse Source 
It has been common practice (in QT5 for example) to set
wl_shell_surface state at situations where mutter will have destroyed
the MetaWindow. This commit keeps track of the relevant state
separately from MetaWindow, and synchronizes when needed.
