The existing data comes under Unicode-DFS-2016 but future updates
shall come under Unicode-3.0, so update the existing headers with the
former and the generator script with the latter. Leave a note in the
attribution file about this transitional state and how to resolve it.
Replaced UNICODE_LICENSE.txt from src/corelib/text/ with
LICENSES/Unicode-DFS-2016.txt, as fetched using reuse download.
This doesn't look like a rename but only actually adds some irrelevant
lines about where on the Unicode website the upstream files (to which
we do not apply this license) come from and changes some spacing.
