typing: add type hints to mercurial/win32.py
These are the low level functions that are imported by the mercurial.windows
module, which is in turn imported by mercurial.utils as the platform module.
Pretty straightforward, but pytype inferred very little of it, likely because of
the heavy ctypes usage. It also seems to trigger a pytype bug in procutil, now
that it has an idea of the underlying function type, so disable that warning to
maintain a working test.
