It would work with the builtin provider, too, which would not require
ICU at all.

The idea is that you could build an extension that copies the same
logic for building the Unicode tables that we have in Postgres now,
except that it uses whatever version of the Unicode data files you
want.

If we want it to be targeted more specifically at the builtin provider,
we can make it even simpler by allowing you to just replace the unicode
tables with an extension (rather than the method tables). I'm not 100%
sure what people actually want here, so I'm open to suggestion.

I'd like to provide options for all kinds of users and packagers.
