Use of the word "Open" in endstop status

I’d like to propose moving away from “Open” and “Triggered” as the two states for Endstops (and other similar devices.

The trouble is, when users have a correctly configured Normally Closed endstop, klipper literally ends up using the word “Open” to refer to the endstop itself being “Closed”, and “Triggered” to refer to it being “Open”. Triggered/open is fine, but Open/Closed is very, very confusing for new users.

About the best I can think of offhand is simply using “Not Triggered” and “Triggered”, Though I’m certainly open to other suggestions.

I’m also happy to submit a P.R., but I figured I’d post this first, just to see if it’s worth pursuing. (and see if anybody can think of a better terminology)
