Geoffrey McRae aa9dbe654d [client] wayland: move libdecor and xdg into seperate backends
This allows us to build with libdecor enabled as the selection to use it
is decided upon at runtime if the compositor `gnome-shell` is detected.
If the libdecor development headers are installed, by default it will
now be compiled in unless overridden by the user at compile time.
