xdg-shell: validate positioner object

According to the xdg-shell v6 protocol a positioner object is only
complete if both the size and its anchor rectangle are set. Ensure the
weston clients do this and let weston be more strict on checking if a
client has done so.

This also fixes weston-terminal popups not showing up on gnome-shell
3.22.
