Continue fixing Py_ to Ty_ renaming - fix missed patterns

Fixed additional patterns that were missed in the initial renaming:
- PyThreadState → TyThreadState (typedef and all uses)
- PyMem_RawFree → TyMem_RawFree
- Py_buffer → Ty_buffer
- Py_CLEANUP_SUPPORTED → Ty_CLEANUP_SUPPORTED
- PyStatus → TyStatus and PyStatus_NoMemory → TyStatus_NoMemory
- _Py__has_builtin → _Ty__has_builtin
- _Py_SINGLETON → _Ty_SINGLETON
- _Py_CODEUNIT → _Ty_CODEUNIT
- _Py_BackoffCounter → _Ty_BackoffCounter
- _Py_slot_* and _Py_type_* patterns

Build is progressing with fewer errors.
