Skip AOT Inductor test_cond_* tests on ROCm (#121522)
Summary: The newly added tests in https://github.com/pytorch/pytorch/pull/121120 are failing in the `ciflow/periodic` jobs. Here we skip those on ROCm to avoid the need to disable those tests manually on ROCm.
Test Plan:
```
$ python test/inductor/test_aot_inductor.py -k test_cond_nested
...
----------------------------------------------------------------------
Ran 6 tests in 72.122s
OK
```
