Update display widths as part of updating Unicode
The hardcoded "wide character" set in ucs_wcwidth() was last updated
around the Unicode 5.0 era. This led to misalignment when printing
emojis and other codepoints that have since been designated
wide or full-width.
To fix and keep up to date, extend update-unicode to download the list
of wide and full-width codepoints from the offical sources.
In passing, remove some comments about non-spacing characters that
haven't been accurate since we removed the former hardcoded logic.
