Shifting from scikit-build to meson

[czgdp1807]

Hi folks. We are considering meson as a build system. It is a simple and modern build system being used by SciPy and NumPy already. It is compatible with all the platforms and is available on conda.

Using meson we can also make distribution C++ tests optional, therefore reducing the download size for the end users and saving a lot of internet bandwidth/energy with the increase in the number of downloads. Already done in NumPy - numpy/numpy#26274 and a work in progress in SciPy - scipy/scipy#20712.
