Don't allow creation of database with ICU locale with unsupported encoding
Check in CREATE DATABASE and initdb that the selected encoding is
supported by ICU. Before, they would pass but users would later get
an error from the server when they tried to use the database.
Also document that initdb sets the encoding to UTF8 by default if the
ICU locale provider is chosen.
