gh-128150: Improve performances of `uuid.uuid*` constructor functions. (#128151)
We introduce a private constructor `UUID._from_int()` for RFC 4122/9562 UUIDs,
which takes the integral UUID value as input. The latter must have correctly set
its variant and version bits. We also make `UUID.__init__()` slightly more efficient.
