pgsql: Catalog changes preparing for builtin collation provider.

Catalog changes preparing for builtin collation provider.

Rename pg_collation.colliculocale to colllocale, and
pg_database.daticulocale to datlocale. These names reflects that the
fields will be useful for the upcoming builtin provider as well, not
just for ICU.

This is purely a rename; no changes to the meaning of the fields.
