This API is available starting in 3.11. It is not part of the Stable ABI.
PyType_GetModuleByDef searches the MRO of the given type for a module
matching the given module spec. It can be useful for users use that
`pyo3_ffi` directly and want to support multiple interpreters/per
interpreter GIL. It is useful to obtain access to the module state from
special methods like `tp_new` that can't use the METH_METHOD calling
convention.
This API is not supported on PyPy yet, but guess the symbol name for the future.
