[bug/performance] Random state is updated even when unused

[awni]

import mlx.core as mx

def fun():
    for _ in range(1000):
        mx.random.randint(1, 10)

fun()
print(mx.random.randint(0, 10, shape=(32, 32)))

Evaluating the last line causes 1k split kernels to run since the internal random state is updated in fun. I am not sure there is an easy fix for that.. but it would be nice to avoid running those superfluous 1k kernels since they are never used.
