RFR: 8376052: Use AttachOperationFailedException rather than AttachNotSupportedException in findTargetProcessTmpDirectory() [v3]

[Yasumasa Suenaga]

> [JDK-8373867](https://bugs.openjdk.org/browse/JDK-8373867) improves the logic to find tmp directory for using in attaching procedure. It might throw `IOException` or `AttachNotSupportedException` when it failed.
> 
> In review thread #28867, we reached conclusion we should use `AttachOperationFailedException` rather than `AttachNotSupportedException` because `AttachNotSupportedException` would be thrown when a compatible AttachProvider does not exist.
