Use test/test-reports for inductor (#88533)
So that the test reports can be picked up automatically by the CI and uploaded to S3. Later on, this will allows the querying of these test reports from our Rockset DB.
For example https://github.com/pytorch/pytorch/actions/runs/3382363153/jobs/5617382531 `Upload test statistics` shows:
```
+ python3 -m tools.stats.print_test_stats --upload-to-s3 --compare-with-s3 test
No tests in reports found in test
```
