make quantized model tests better

Summary:
XNNPACK should be testing with random inputs and quantized models should be calibrated before lowering and testing. Right now there are some numerical issues being debugged and tracked by: T187799178. this has been a bit difficult, but for now, we can first make these tests better by giving random inptus and enabling calibration.  

We don't fix the numerical issues in this diff.
