CREATE DATABASE: make LOCALE apply to all collation providers.
For CREATE DATABASE, make LOCALE parameter apply regardless of the provider used. Also affects initdb and createdb --locale arguments. Previously, LOCALE (and --locale) only affected the database default collation when using the libc provider.
