[release/2.14] UT inductor Windows fatal exception: access violation in unload_xpu_triton_pyds

### 🐛 Describe the bug

Issue found during pre RC test with torch 2.14.0.dev+xpu on Windows with Intel XPU.

339 UTs across 5 `pytorch\test\inductor\*` test files crash on Windows with Intel XPU with a native **access violation** (exit code `3221225477` / `0xC0000005`). The crash does not happen inside the test body but during test teardown, in `torch/_inductor/utils.py::unload_xpu_triton_pyds` called from `fresh_cache`. Because the worker process dies, every affected test is reported as `FAILED CONSISTENTLY`.

### Affected Test Cases

339 tests fail with this crash, broken down by file:

```
test/inductor/test_codecache.py 164
test/inductor/test_compiled_optimizers.py 85
test/inductor/test_triton_kernels.py 52
test/inductor/test_compiled_autograd.py 22
test/inductor/test_torchinductor.py 16
```

Representative cases:

```
