Add force-blocking-launches to run_compute_sanitizer_test script (#20962)

The weekend compute-sanitizer runs are failing with segfaults which cannot be reproduced locally.
It is possible that `compute-sanitizer` itself is running out of memory:
 https://docs.nvidia.com/compute-sanitizer/ComputeSanitizer/index.html#memory-footprint
Adding the `--force-blocking-launches` as recommended in this PR.
