[xCluster] DDL Replication - Handle cleanup of colocated_historical_schema_packings for failed source tables

[hulien22]

Jira Link: DB-15225
If a source table fails during creation, we will still get a CMOP with the initial schema - this will be replicated via automatic DDL replication and this initial schema will be stored in colocated_historical_schema_packings.

Typically, this field is cleared upon a successful target table creation, but in this case, there will not be any target creates.. Thus we need some separate cleanup handling function

Need to look into what CMOPs we do receive in these cases, perhaps we can notice the drop and delete the field then.
Also should ensure that repeated colocation ids are handled properly
