[DDP] Fixes flaky tests caused by incorrect floating-point comparison (#56192) Summary: Fixes https://github.com/pytorch/pytorch/issues/50699. The root cause was that some floating-point assertions had a "greater than or **equal to**" condition. The "equal to" part was causing flakiness due to strict equality check (`==`) in `TestCase.assertGreaterEqual()`. This PR introduces a new assertion method called `assertGreaterAlmostEqual()` in `common_utils.py` that mitigates the problem by behaving similar to `TestCase.assertAlmostEqual()`.
