Also use text-input if QT_IM_MODULE is empty or "wayland"

Previously, text input can only be used when only when QT_IM_MODULE is
unset, it is counter-intuitive when empty and null has different meaning.
Additionally making "wayland" to use text input to make it easier to enforce
wayland context. Gtk's relevant value is also "wayland" so it will be more
consistent.

Pick-to: 6.4 6.3 6.2
