Jonathan Tran ddb034b14d Show KCL backtraces (#7033)
* Add backtrace to errors

* Add display of backtraces with hints

* Change pane badge to only show count of errors

* Fix property name to not collide with Error superclass

* Increase min stack again

* Add e2e test that checks that the diagnostics are created in CodeMirror

* Remove unneeded code

* Change to the new hotness
