This change is strictly renames and moving code around. It helps in the following ways: * ensures type-related init functions focus strictly on one of the three aspects (state, objects, types) * passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter * consistent naming conventions help make what's going on more clear * keeping API related to a type in the corresponding header file makes it more obvious where to look for it https://bugs.python.org/issue46008
