pytype: stop excluding mercurial/ui.py

ui.extractchoices() is perhaps making assumptions that it shouldn't about the
pattern always matching, but presumably we have test coverage for that.

PyCharm flags the updated classes with a warning "Class xxx must implement all
abstract methods", and suggests adding `abc.ABC` to the superclasses.  I'm not
sure why, unless it doesn't recognize the `__getattr__()` delegation pattern.
Additionally, we can't unconditionally subclass `typing.BinaryIO` because that
defeats the `__getattr__` delegation to the wrapped object at runtime.  Instead,
it has to only subclass during the type checking phase[1].

In any event, this fixes:

    File "/mnt/c/Users/Matt/hg/mercurial/ui.py", line 1518, in _runpager:
        Function subprocess.Popen.__new__ was called with the wrong arguments [wrong-arg-types]
             Expected: (cls, args, bufsize, executable, stdin,
                        stdout: Optional[Union[IO, int]] = ..., ...)
      Actually passed: (cls, args, bufsize, stdin,
                        stdout: Union[mercurial.utils.procutil.WriteAllWrapper,
                                mercurial.windows.winstdout], ...)
    File "/mnt/c/Users/Matt/hg/mercurial/ui.py", line 1798, in extractchoices:
