Test matrix strategy for deployment

[Andful]

From my understanding, to solve issue #35 and #37 require a "matrix" like deployment.

This draft is for me to test the matrix feature of the GitHub pipeline. Hopefully, if acceptable, it may be merged.

This is the most "successful" action so far: https://github.com/Andful/scipoptsuite-deploy/actions/runs/23714480464

They seem to compile and pass the test for all the cases (with and without GMP), except for windows. On windows, I have trouble compiling SCIP. (Note, in the actions, all jobs seem to be successful because I disabled set -e to avoid the other jobs to be stopped.)

On windows, I am having problems compiling SCIP. From the error message, it seems to be somehow related Ipopt. It would be great if I can get pointers to fix the compilation error. FYI ... I moved away from the MSVC compiler into the GCC compiler. This because, MSVC does not seem to be supported for the GMP project.

The things I could achieve are:

• Unify the jobs between the OS and architectures. I think this is needed for Have options for default, performance, and debug pyscipopt #35 and Deploy with exact solving #37, where addition of a boolean parameter does not require very similar changes across job anymore. By unifying the jobs, addition of a boolean parameter require a singular(-ish) change to 1 job.
• Compilation of GMP. GMP compiles successfully and the test pass for all architectures and OSs.

Few miscellaneous points:

• If we keep the GCC compiler for windows, and compile most of the dependencies from source, we may unify the building processes across architectures and OSs. Only "diverging behavior" across architectures and OSs being dependence installation.
• I broke the feature where you could conditionally select which OSs to build for 😅. One simple solution to fix this may be the "return early".
• The way I unified the jobs is a bit "hacky"...

P.S.

On windows, I compiled Ipopt from source. The compilation of Ipopt seems to complete just fine. But when compiling SCIP, I get the following logs of this job:

EDIT:
nvm....Ipopt does not seem to have compiled:
