Some mixin methods in `collections.abc` are not mentioned in the Document

Set

Set.__rsub__ and Set.__rxor__ do exist but not mentioned in the Document.

MappingView

MappingView.__init__ and MappingView.__repr__ have the same issue.

But since __init__ and __repr__ always have default implementation in the base class object, so I'm not sure should we treat them as mixin methods. But the implemntation in MappingView do have it's own logic so I assume they should be mixin methods.
