Remove arguments of _forward_eval_ϵ

They are always the same anyway. I wonder if there is any performance benefit of saving these interpret calls. Is there a standard benchmark used for checking for regressions ?
Maybe https://github.com/lanl-ansi/rosetta-opf/blob/main/jump.jl ?

Yes that, with a much larger instance, say https://github.com/power-grid-lib/pglib-opf/blob/master/pglib_opf_case30000_goc.m

Or build that model and then manually evaluate the Hessian with MOI.eval_hessian_lagrangian etc.

When I refactored this out of JuMP, I tried to make the fewest possible changes. The code can be cleaned up lots.

Yes, we could add a reduced version to MOI.Benchmarks
