windows/mkwinsyscall: account for non-"err" return values when processing "?"

The "?" code assumed that the error value was always called "err", when
in reality it might be called something different (like "ret") or even
entirely absent. This commit makes the templating robust to that. At the
same time, we move a lot of the complexity out of the actual templates
and into helper functions, so that this remains easy to read.
