[3.12] gh-97959: Fix rendering of routines in pydoc (GH-113941) (GH-115296)

* Class methods no longer have "method of builtins.type instance" note.
* Corresponding notes are now added for class and unbound methods.
* Method and function aliases now have references to the module or the
  class where the origin was defined if it differs from the current.
* Bound methods are now listed in the static methods section.
* Methods of builtin classes are now supported as well as methods of
  Python classes.

+Fix rendering class methods, bound methods, method and function aliases in
+:mod:`pydoc`. Class methods no longer have "method of builtins.type
+instance" note. Corresponding notes are now added for class and unbound
+methods. Method and function aliases now have references to the module or
+the class where the origin was defined if it differs from the current. Bound
+methods are now listed in the static methods section. Methods of builtin
+classes are now supported as well as methods of Python classes.
