One mitigation for the Ventura linking problem (DM-37301) could be to reduce the number of shared libraries we are linking against. Import of  shapelet can trigger the linking problem in Ventura and would be a good place to experiment since there are currently 11 separate pybind11 interface files being loaded (each of those linking against many shared libraries).

This ticket is to combine them into a single shared library, similar to what was done with sphgeom in DM-25877. This should have the side effect of making the build faster and also improving import time in general.
