Do State FBs Need an EPICS "STOP" input?

[ZLLentz]

Current Behavior

To stop a state mover, you need to "stop" the raw motor. There is no API provided to request a stop from the state FB.

Expected Behavior

Is this a glaring omission or is it ok?

Context / environment

I was testing typhos screens and I noticed that none of the state devices had stop buttons and one thing led to another...

It might be time to add this in since state motors can have arbitrarily many motors now...
