IMPALA-9529: Fix multi-tuple predicates not assigned in column masking

Column masking is implemented by replacing the masked table with a table
masking view which has masked expressions in its SelectList. However,
nested columns can't be exposed in the SelectList, so we expose them
in the output field of the view in IMPALA-9330. As a result, predicates
that reference both primitive and nested columns of the masked table
become multi-tuple predicates (referencing tuples of the view and the
masked table). Such kinds of predicates are not assigned since they no
longer bound to the view's tuple or the masked table's tuple.

We need to pick up the masked table's tuple id when getting unassigned
predicates for the table masking view. Also need to do this for
assigning predicates to the JoinNode which is the only place that
introduces multi-tuple predicates.

Tests:
 - Add tests with multi-tuple predicates referencing nested columns.
 - Run CORE tests.
