raylib: use stable ABI for CFFI extension (#37)

The CFFI extension was built with py_limited_api=False, producing
version-specific .so files (e.g., cpython-312 on Linux, cpython-314
on macOS). This caused import failures when the build Python version
didn't match the runtime version.

Switch to py_limited_api=True to produce _raylib_cffi.abi3.so which
works across Python 3.x versions.
