winewayland.drv: Ensure outputs can access xdg information robustly.

Add outputs to the output_list on creation (instead of when they are
first configured), so they are detected and "upgraded" with xdg
information even if the compositor advertises the zxdg_output_manager
global after the wl_outputs themselves.
