Switch use of Py_INCREF to new Py_NewRef function

Browse Source 
This is more idiomatic, simplifies the code, makes it easier to port to eg. HPy later on, and makes it easier to use the limited ABI (where it can be optimized to a tail call) later on

A polyfill is provided for compatibility with Python versions 3.8 and 3.9
