luwrap: replace Nim unicode maps with libunicode

Instead of using the built-in (and outdated, and buggy) tables, we now
use libunicode from QJS.  This shaves some bytes off the executable,
though far less than I had imagined it would.

Also, a surprising effect of this change: because libunicode's tables
aren't glitched out, kanji properly gets classified as alpha.  I found
this greatly annoying because `w' in Japanese text would now jump
through whole sentences.  As a band-aid solution I added an extra
Han category, but I wish we had a more robust solution that could
differentiate between *all* scripts.

TODO: I suspect that separately loading the tables for every rune in
breaksViWordCat is rather inefficient.  Using some context object (at
least per operation) would probably be beneficial.
