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.
