What's changed and what's your intention?

resolve #17245

This PR adds support for pg_index_column_has_property function to query index column properties.

Currently we have property asc, desc, nulls_first, nulls_last. But they are not stored in the index catalog. This PR also adds them to the catalog.

Thanks! LGTM
I never expected that we had to implement migration logic in order to adding a system table.
