This makes sense to me, but I'd like someone from libs-api to take a look. r? libs-api |

Windows: make `read_dir` stop iterating after the first error is encountered This also essentially makes the `ReadDir` iterator fused. Which I think is pretty much what people expect anyway. [`FindNextFileW`](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-findnextfilew) doesn't document what happens if you call it after iteration ends or after an error so we're probably in implementation defined territory at that point.
