Motivation

reduce the number of solvers we need to maintain

@martinjrobins It would be nice to break out idaklu into its own package within the PyBaMM ecosystem. That would let PyBaMM just install it as a library similar to how we install a casadi package. Is it feasible to do that along with removing the old solver?

Note for other readers: this was discussed in the monthly developer meeting in April and in the recent v24.5 release prep meeting. @Saransh-cpp reported that this could be a suitable 175-hour GSoC project
