unicode: improve generated comments for categories

Browse Source 
The comments on the category range tables in the unicode package are fairly
redundent and require an external source to translate into human readable
category names.

This adds a look up table with the category descriptions and uses it if
available when generating the comments for the range tables.

Fixes #28954
