        Wraps a target instance and an AutoCloseable delegate into a proxy instance that closes both when wrapper close method called.
        Type Parameters:
        T - The generic AutoCloseable wrapping interface
        Parameters:
        proxyTarget - The (never null) target instance - if not AutoCloseable then it's close() method will not be invoked (i.e., only the delegate)
        type - The target wrapping interface
        delegate - The (never null) delegate to close. Note: the delegate is closed after the target instance.
        Returns:
        The wrapping proxy
