spinRow: Consider adding set_range

https://docs.gtk.org/gtk4/method.SpinButton.set_range.html

What was a set_range with GtkSpinRow before is now a set_lower, set_upper, and set_value with min(upper, max(lower, value)) as argument.

Another candidate is set_increments, but that one is significantly less annoying.

Alternatively, those could be added to GdkAdjustment.
