      Description

      In FLINK-12999 I found a case that the planner can't generate a valid execution plan for a sample query:

      SELECT UUID() FROM (VALUES(1, 2, 3)) T(a, b, c)

      I made an investigation and found the root case was: RexCall's Monotonicity is not considered in determining a Calc's collation( should do the same as Project).
