[7.0] Fix reporting of an async IO timeout error on Windows (`SerialP…

…ort`) (#81745)

- Port of #81744
- When an async `SerialPort` IO operation times out, it reports the timeout in the IO completion with an `NTSTATUS` value of `WAIT_TIMEOUT` (258)
- In the thread pool when using `GetQueuedCompletionStatusEx`, the `NTSTATUS` value was being checked against `STATUS_SUCCESS` to determine success, so the `WAIT_TIMEOUT` was reported as an error. This leads to a different exception being thrown, compared to before when `GetQueuedCompletionStatus` was used.
- Fixed to use similar logic to the SDK's `NT_SUCCESS` macro, which treats the `WAIT_TIMEOUT` value as a success, which is similar to what `GetQueuedCompletionStatus` does
- There are already tests that verify this behavior in `System.IO.Ports` tests, though [they are currently disabled](https://github.com/dotnet/runtime/blob/b39d6a6eb44860746e91e5ce4f585beff33d1f63/src/libraries/System.IO.Ports/tests/Support/TCSupport.cs#L108-L118) due to instabilities. I have verified locally that the relevant failures are fixed and that there are no new failures in those tests.
