unicode: Add utf8-data module

Browse Source 
utf8data.h contains a large database table which is an auto-generated
decodification trie for the unicode normalization functions.

Allow building it into a separate module.

Based on a patch from Shreeya Patel <shreeya.patel@collabora.com>.

This contains a large table of case foldings, which can be loaded as
a separate module if you say M here. To be on the safe side stick
to the default of Y. Saying N here makes no sense, if you do not want
utf8 casefolding support, disable CONFIG_UNICODE instead.
