[dtensor] enable op db tests by using multithreaded test case (#92198) Time comparison between using MultithreadedTestCase and MultiProcessTestCase on op db tests is amazing! using MultiThreadTestCase on a AWS dev node: ``` time pytest test/distributed/_tensor/test_dtensor_ops.py ============= 175 passed, 42 skipped, 397 xfailed in 80.30s (0:01:20) ======= real 1m22.330s user 1m38.782s sys 0m18.762s ``` MultiProcessTestCase spends from 40mins to more than 1h, even if using pytest parallel testing tools.
