[CI][TorchModels] Update SDXL int8 model CI (1/2) (#22621)

We have newly exported MLIR that should be faster than the old MLIR. It
has a different entry point and signature, so we can't update the tests
exactly since we don't have generated input/output updated yet. For now
I've updated the compstat test and made a new test that uses random
inputs.
