78f04477 - [mlir][python] declare `_PyClassMethod_New` undefined at link time (#121597)

[mlir][python] declare `_PyClassMethod_New` undefined at link time (#121597) `NanobindAdaptors.h` uses `PyClassMethod_New` to build `pure_subclass`es but nanobind doesn't declare this API as undefined in its linker flags. So we need to declare it as such for downstream users that do not do something like `-undefined dynamic_lookup`
