pgsql: Add target_relid parameter to pg_get_publication_tables().

Add target_relid parameter to pg_get_publication_tables().

When a tablesync worker checks whether a specific table is published,
it previously issued a query to the publisher calling
pg_get_publication_tables() and filtering the result by relid via a
WHERE clause. Because the function itself was fully evaluated before
the filter was applied, this forced the publisher to enumerate all
tables in the publication. For publications covering a large number of
tables, this resulted in expensive catalog scans and unnecessary CPU
overhead on the publisher.

This commit adds a new overloaded form of pg_get_publication_tables()
that accepts an array of publication names and a target table
OID. Instead of enumerating all published tables, it evaluates
membership for the specified relation via syscache lookups, using the
new is_table_publishable_in_publication() helper. This helper
correctly accounts for publish_via_partition_root, ALL TABLES with
EXCEPT clauses, schema publications, and partition inheritance, while
avoiding the overhead of building the complete published table list.

The existing VARIADIC array form of pg_get_publication_tables() is
preserved for backward compatibility. Tablesync workers use the new
two-argument form when connected to a publisher running PostgreSQL 19
or later.

Bump catalog version.
