Investigate a better way to repair wheels for Linux and macOS

[agriyakhetarpal]

The addition of pyproject.toml in #3301 presented a hacky way to find the CasADi dynamic libraries or shared object files at the time of repairing the wheel, but the ideal method would be to adjust the runtime search path for the idaklu target and build the wheel using a different frontend instead of pip, i.e., using python -m build. This would make repairing the wheel easier since the target can look at the right path to find the libraries, whereby casadi can be pre-installed to counter PEP517/518 build isolation at the time of building wheels.
