Crash when printing array that contains itself

Godot version

3.4 / 4.0

System information

W10

Issue description

When you do do

var a = []
a.append(a)
print(a)

Godot will crash.

I checked how Python handles it and it prints [[...]].

Regression from #35816. I've tested on 3.4 and it works fine since it doesn't have these changes yet.

I have incremented the recursion_count which fixes the issue, but the output has changed to:
[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[...]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]
(aka 100 recursions before the trigger is called, returning [...])

@touilleMan I see that the PR was to change the ==/!= behavior specifically. Do you think, for the stringify method, the old stack behavior can be reverted, or is there a reason for it's changes too? I've been trying some ideas on how to fix this but I haven't found a clean way to do it, and I think it's gonna be hard to fix this properly under these new changes.
