Pyosys Wheels
* Created `setup.py`: Python package manifest to build `pyosys` wheels with a custom extension to build and include `libyosys.so` using Make * `.gitignore`: Added byproducts of the Python wheel build process * `Makefile`: Added `-undefined dynamic_lookup` to `libyosys.so` so missing symbols can be resolved by importing into a Python interpreter * `kernel/yosys.cc`: Gated `PyImport_AppendInittab` with `!Py_IsInitialized`; as of Python 3.12, the interpreter is already initialized and `PyImport_AppendInittab` would cause an exception to be raised * Created `wheels.yml`: CI workflow for building wheels for CPython on: * Linux (glibc, musl) and Darwin * x86-64 and arm64
