Hide Normals on Hidden Faces

Normals are displayed no matter what the Hidden state of their faces. This clutters up the viewport with lines that the user has already indicated they aren't interested in.

While I think use cases for both hiding a Face while wanting to see the normal would be rare, it could indeed be optional.

But I think that when most users, in most cases (like, 99%+) Hide a Face, they are no longer interested in the normal for that face. So, normals should be hidden when their Faces are hidden.
