    gh-108751: Add copy.replace() function (GH-108752)
    
    It creates a modified copy of an object by calling the object's
    __replace__() method.
    
    It is a generalization of dataclasses.replace(), named tuple's _replace()
    method and replace() methods in various classes, and supports all these
    stdlib classes.
