remove debug modes for python

[mjkkirschner]

Purpose

This PR removes the debug modes for Ironpython obsolete and python engine selection ui. So these features are now enabled by default.

Tests are updated to no longer set the debug mode and the test config is removed.

IronPython warnings will now be raised when opening dyn/dyfs unless the preference for suppressing them is selected or the session per graph "do not show again" checkbox is enabled.

@mjkkirschner It looks fine. I think we discussed before the context menu of engine switch being a temp solution. With now we have count down of removing IronPython OOTB, do you think we can slowly remove the engine switches from context menu?

LGTM!

sure @QilongTang @Amoursol - though it does seem pretty useful to change versions without opening the editor... defer to you guys of course - let me know if you want me to remove it in this PR?

hmm after thinking about it, I feel let's not touch the scope of this PR. I will log a Jira and put into backlog. It might be worth to check the actual behavior with IronPython removed, what does the switch do. I will add that in that task.

@mjkkirschner @QilongTang I concur with the above commentary :)
