refactor: add
isActive to ErrorMessageID
Currently there is no way to tell if a given `ErrorMessageID` is emitted at all from the compiler. While working on an index of all the IDs I keep needing to dig into the code to see if there is a message that uses an `ErrorMessageID` and then see if that message is actually used anywhere. From what I can gather so far, the ones that I've marked as `false` are no longer emitted and therefore marked `isActive = false`. refs: scala#14904
