Changes to internal structs in Include/internal/pycore_*.h cause false positive ABI violations in make check-abidump because these types are transitively reachable from public APIs like PyInterpreterState. The internal struct layout is not part of the public ABI contract. This adds a suppression specification file that filters out types defined in pycore_*.h files using a regex pattern, and explicitly suppresses PyInterpreterState, _PyRuntimeState, and PyThreadState which are public typedefs aliasing internal structs. The Makefile is updated to pass the suppression file to abidiff.
