Add `MLIR_ENABLE_PYTHON_STABLE_ABI` cmake flag to build bindings against the Python limited/stable API (abi3 / PEP 384). This allow for compatibility across different >=3.12 versions with a single .so / wheel. We also require CMake >=3.26. The stable ABI restricts usage to a subset of the CPython C API: frame and code object structs are opaque, so introspection APIs like `PyCode_Addr2Location`, `PyFrame_GetLasti`, and `PyFrame_GetCode` are unavailable. The traceback-based auto-location logic is dropped because we don’t have stable ABI to produce complete locations. Assisted-by: claude
