[WIP] add initial version of OptimizationIpopt

[SebastianM-C]

This pacakge directly uses the C interface in Ipopt.jl.
The implementation is based on OptimizationMOI, but it also adds Ipopt specific elements, such as the callback handling.

This PR is an initial draft and needs more work.

The advantage of this approach over OptimizationMOI is that

• we get correct, solver specific callback handling
• support for common maxiters, maxtime, abstol arguments
• slightly lower loading times by not needing to load MOI

While I copied a bit of the code for handling of symbolic systems since I'm not sure I understand how it's working yet and why do we essentially re-implement SymbolicUtils' codegen.

I think that some of the functionality of OptimizationMOI might be common enought that can be moved to an upstream pacakge to avoid code duplication.

I tried to give credit to the autohors of the funtionality that I copied over from OptimizationMOI by includding them as co-authors on the commit. Let me know if that's okay.
