Report enforce predicate in JDBC connectors' getTableProperties

[findepi]

Once we do #4111 we should enhance io.prestosql.plugin.jdbc.JdbcMetadata#getTableProperties
to return information about enforced predicate.

Depends on #4111.

I scenario where this could be visible is

SELECT *
FROM (SELECT * FROM table_a WHERE ak = 42)
INNER JOIN  (SELECT * FROM table_b WHERE bk = 42) ON ak = bk

Once we push predicates into JDBC table scan, we need getTableProperties
to let the optimizer know that the join is actually a cross join.
