glyph-util: bring glyphs into same order everywhere

glyph-util: bring glyphs into same order everywhere

The enum definition, the two string tables and the test all were using
different orders (and in case of the test even missed entries).

Let's unify this, and make sure we always use the same order. This
settles the confusion, and makes the order used for the unicode string
table the canonical one, adjusting the other lists to match it. And adds
the missing entries to the tets.
