Minor optimization for Fractions.limit_denominator (GH-93730)
When we construct the upper and lower candidates in limit_denominator,
the numerator and denominator are already relatively prime (and the
denominator positive) by construction, so there's no need to go through
the usual normalisation in the constructor. This saves a couple of
potentially expensive gcd calls.
Suggested by Michael Scott Asato Cuthbert in GH-93477.
