PYMUPDF_SETUP_PY_LIMITED_API
If not '0', we build for current Python's stable ABI.

However if unset and we are on Python-3.13 or later, we do
not build for the stable ABI because as of 2025-03-04 SWIG
generates incorrect stable ABI code with Python-3.13 - see:
https://github.com/swig/swig/issues/3059

PYMUPDF_SETUP_URL_WHEEL
If set, we use an existing wheel instead of building a new wheel.
