Is fiddling with dl open flags still needed in `dolfinx/init.py`? #2835

See https://github.com/FEniCS/dolfinx/blob/main/python/dolfinx/__init__.py#L10-L25

git blame says it came in 6 years ago when pybind11 wrappers were first prepared for dolfin.

Around six months ago I realized that this was causing problems on Colab, and have a patch in https://github.com/fem-on-colab/fem-on-colab/blob/main/fenicsx/patches/06-do-not-fiddle-with-dlopenflags-in-dolfinx to drop it when packaging there.

With the wrappers moving from pybind11 to nanobind, now seems a good time to raise this issue.

From memory, it was for Numpy and how it links with BLAS/Lapack.
