Remove elephant foot compensation limitation

[bitingsock]

Is your feature request related to a problem? Please describe.
Elephant foot compensation not being able to reduce below 2 perimeter widths is constraining.

Describe the solution you'd like
Removal or override for this behavior.

Describe how it would work
Revert the limitation introduced in 2.2.0 or add checkbox for the logic. With the consideration that #1757 (comment) (<the comment) does not happen; hopefully, as supermerill says, it was just a thin wall problem.

Describe alternatives you've considered
Limiting to a single line is acceptable.

Additional context
I would make the point that with the inclusion of arachne this behavior should be opened back up. Consolidating to a single line is useful sometimes and arachne can make it wider to split the difference.
Personally, I don't like the limitation and prefer to look for these problems on my own, though I suppose most others would not.
Moreover, this limitation was never forced on normal XY compensation and thus seems arbitrary.

Thanks for the interesting idea and the link to the Super Slicer discussion that describes the thin wall improvement and elephant foot compensation.
