Teach tid-scan code to make use of "ctid = ANY (array)" clauses, so that

"ctid IN (list)" will still work after we convert IN to ScalarArrayOpExpr.
Make some minor efficiency improvements while at it, such as ensuring that
multiple TIDs are fetched in physical heap order.  And fix EXPLAIN so that
it shows what's really going on for a TID scan.
