gtk/imwayland: Use serial to control outbound messages

Browse Source 
Following the text-input protocol changes at
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/115,
use the serial number to have the client push changes to the
zwp_text_input_v3 object only after compositor/client states match.

This specifically is more lenient to compositors pushing multiple
.done events ahead of the client replying to them.

(cherry-picked from commit f108f053d4c84dcdedce005a3491cbd503092185)

Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4853
