[issue14386] Expose dictproxy as a public type

[R. David Murray]

R. David Murray <rdmurray at bitdance.com> added the comment:

I believe it was actually Guido who suggested exposing dict_proxy, in response to Victor (but independent of Victor's needs, if I understood the message correctly).

It has always seemed odd to me ("always" referring my time working with Python3, of course) that a class that implements the mapping protocol has no way to return the same type of objects that real dict methods do.
