Add support for rawFonts loaded from data in FaceId

The problem was that with an empty filename and index of 0, all raw fonts
loaded from data had the same FaceId, and we wouldn't bother to load
another one after doing this once.
This commit introduces a uuid in FaceId to help distinguish them in
that case.
