I'm seeing a failure on hoverfly:

https://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=hoverfly&dt=2023-03-09%2021%3A51%3A45&stg=initdb-en_US.8859-15

That's because ICU always uses UTF-8 by default. ICU works just fine
with many other encodings; is there a reason it doesn't take it from
the environment just like for provider=libc?

Of course, we still need to default to UTF-8 when the encoding from the
environment isn't supported by ICU.

Patch attached. Requires a few test fixups to adapt.

  1. initdb: derive encoding from locale for ICU; similar to libc.

  2. Use ICU by default at initdb time.
