Xu Han b2553a6ec4 [AOTI] raise PyTorchStreamWriter open failed error code on windows (#162799 )

When I debug AOTI UT: `TestAOTInductorPackage_cpu::test_add`.  I found it didn't output the verbose error code, when PyTorchStreamWriter open failed.

This PR add the verbose error code output for debug. Local test shows as below:

The error code is 32, we can check the Windows error code 32 at https://learn.microsoft.com/en-us/windows/win32/debug/system-error-codes--0-499-
```
ERROR_SHARING_VIOLATION
32 (0x20)
The process cannot access the file because it is being used by another process.
```

This issue is caused by the file is opened by another process. I fixed same issue in zip open as PR: https://github.com/pytorch/pytorch/pull/162617 But still no idea how to open file with shared access in `std::ofstream`. I will continue to researching it.
