gh-158666: Avoid copy if shutil.move fails other than EXDEV

[ptim0626]

• Issue: shutil.move creates copy if rename fails with errors unrelated to EXDEV #158666

[ptim0626]

I am not entirely sure how Windows handles unwritable directory (or if there is such concept in Windows at all), as it seems the failed CI all related to directory not set to unwritable in Windows via chmod.

After some thoughts I think the cleanest way to test is just to mock os.rename to return PermissionError (or other exceptions but not EXDEV), although it might be possible to use some commands in Windows with a subprocess to set file/directory as non-writable (os.chmod seems not working quite well with Windows), it may overcomplicate things and I am not familiar with those Windows commands...
