Fix intra-query memory leakage in nodeProjectSet.c.
Both ExecMakeFunctionResultSet() and evaluation of simple expressions
need to be done in the per-tuple memory context, not per-query, else
we leak data until end of query. This is a consideration that was
missed while refactoring code in the ProjectSet patch (note that in
pre-v10, ExecMakeFunctionResult is called in the per-tuple context).
Per bug #14843 from Ben M. Diagnosed independently by Andres and myself.
