Fix materialized_views filters when listing relations

Before the change, the `list_relations_without_caching` macro queried
`system.metadata.materialized_views` with no effective filter on the
catalog and schema name. In theory the Trino optimizer could figure out
the effective predicate on the `system.metadata.materialized_views`
table, but in practice it was not happening, and all materialized views
from all catalogs where being pulled.
