RFR: 8345144: Robot does not specify all causes of IllegalThreadStateException [v3]

[Alisen Chung]

> When robot.autoWaitForIdle is set to true, all mouse and key-related methods when invoked on the EDT will throw java.lang.IllegalThreadStateException which is not in the Robot specification.
> 
> This PR updates the specification by adding warnings to avoid calling lengthy and delay-type methods on EDT and including exceptions thrown when autoWaitForIdle is set to true and mouse/key-handling methods are called on the EDT.
