weston_10.0_aglcore.inc: Update wl_output to version 4

This allows clients to query the output name and description name as
seen by the compositor. Previously this was only possible only with
xdg_output_manager extension but a recent update to the core wayland
protocol allows us to do just that.

Patch is posted upstream
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/987, but
will take some time to get in, as we're in the process of a release.

+Subject: [PATCH] libweston: Send name,description, update wl_output to ver 4
+
+These have been in wayland a while back with version 1.20.0.
+
+We also need to update the test client helper with this bump, as
+those bind to version 4.
