[docs] [issue30396] Document the PyClassMethod* C API functions.

[Decorater]

New submission from Decorater:

The way the documentation currently is set up there is no way to know what these functions in the C API actually do or what all the parameters are to call it unless someone source dives into python. Because of this I think making an C API page or a section for the functions like these or similar capabilities would be an Great an huge help to others as well as an example small module using said PyClassMethod* functions.

I will need to look at how far down in python versions that these functions exist for though.
