[luatex] Reading registry to find Windows fonts

[Philipp Stephani]

A few years ago I implemented a library to retrieve the list of fonts on
Windows, OS X, and Linux: https://www.ctan.org/pkg/lualatex-platform
I don't think it's widely used, but when I wrote it it worked reliably an
all three OSes (http://tracker.luatex.org/view.php?id=555), and could be
used as a starting point.
