A cleanup for MDEV-19908 Add class Type_collection
If we have a mixture of: - a MariaDB standard (built-in permanent) data type, and - a non-standard (optionally compiled or pluggable) data type, then ask the type collection of the non-standard type to aggregate the mixture. If the non-standard collection fails, then continue aggregation with Type_handler_data.
