Fix type construction issues

Summary:
A couple of issues around defining static types in 3.14:
1) We can't use `_PyObject_GenericSetAttrWithDict` to set attributes as there's an assertion it doesn't get called for types.
2) 1UL << 2 is now Py_TPFLAGS_INLINE_VALUES, we need to use a different free value.
