Do not allow nullable arrays, which were not correctly implemented

Browse source 
Nullable arrays, which are not used anywhere, were marshalled the same
way as an empty non-null array. The demarshalling logic did not
recognize anything as a null array. Given this, it seems better to just
explicitly not support it.

Fixes https://gitlab.freedesktop.org/wayland/wayland/-/issues/306.
