Replace lateral references to removed rels in subqueries
This commit introduces a new field 'sublevels_up' in ReplaceVarnoContext,
and enhances replace_varno_walker() to:
1) recurse into subselects with sublevels_up increased, and
2) perform the replacement only when varlevelsup is equal to sublevels_up.
This commit also fixes some outdated comments. And besides adding relevant
test cases, it makes some unification over existing SJE test cases.
