RFR: 8320328: Restore interrupted flag in ImageIcon.loadImage [v4]

[Rajat Mahajan]

> ImageIcon.loadImage used to handle InterruptedException only by printing a message to the console. JDK-8236987 handled the interrupted state more gracefully, but it didn't restore the interrupted flag.
> This change restores the interrupted flag that will allow the following code to handle interruption and exit the thread; otherwise, the thread will continue to run.
