wayland: Don't create zxdg toplevel decoration twice Each window can have at most one zxdg toplevel decoration, but as of [1], we accidentally create two. (If libdecor is not in use). This causes wayland windows with server-side decorations (e.g. on KDE/KWin) to crash with the message: zxdg_decoration_manager_v1@7: error 1: decoration has been already constructed This extra zxdg_decoration_manager_v1.get_toplevel_decoration() call was introduced while deprecating wl-shell and xdg-shell-stable[1] support, and possibly was a bad interaction with [2], which moved the decoration creation around. Fixes: 6aae5b44f8 ("Remove wl-shell and xdg-shell-unstable-v6 support (#4323)") [1]: https://github.com/libsdl-org/SDL/pull/4323 [2]: https://github.com/libsdl-org/SDL/pull/4374
