Move sharding_ddl_util.cpp into sharding_catalog_manager target

As a precondition to be able to use sharding ddl utils in the config server for SERVER-57060, the sharding_ddl_util.cpp dependency needs to be moved under the sharding_catalog_manager target.

Since dropCollectionLocally is linking libraries not included by the catalog manager, move it out of the ddl utils and make it a static function of the DropCollectionCoordinator.
