This is an alternative to #120650 where UUIDv7 features monotonous properties.
There's still the question on the semantics of the time-fields since they are no more compatible with UUIDv1 (actually, the docs are rather imprecise since they do not say that
time_lowfor a non-UUIDv1 is not meaningful). For design discussions on this, I'd prefer doing it on #120650.📚 Documentation preview 📚: https://cpython-previews--120830.org.readthedocs.build/
