Add a helper function to determine if a seat has a (physical) touchscreen associated with it. Currently src/backends/meta-backend.c has a private version of this (check_has_physical_touchscreen) and further patches in this patch-set need the same functionality. So add a generic helper for this to avoid code duplication. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
