[api-minor] Initialize the unicode-category *lazily* on the Glyph-instance

Browse source 
The purpose of this patch is twofold:
 - Initialize the unicode-category data *lazily* during text-extraction, since this is completely unused during general parsing/rendering.
 - Stop exposing this data in the API, since it's unused on the main-thread and it seems like it was *accidentally* included.

Obviously these changes are API-observable, but hopefully no user is depending on this. Furthermore, it's trivial for a user to re-create this unicode-category data manually with a regular expression (from the exposed `unicode` property).
