Handle new option colliculocale in CREATE COLLATION logic
In PG15, there is an added option to use ICU as global locale provider. pg_collation has three locale-related fields: collcollate and collctype, which are libc-related fields, and a new one colliculocale, which is the ICU-related field. Only the libc-related fields or the ICU-related field is set, never both. Relevant PG commits: f2553d43060edb210b36c63187d52a632448e1d2 54637508f87bd5f07fb9406bac6b08240283be3bmulti_shard_json_table
