morrySnow 8ee7bc430d [fix](Nereids) should derive stats asap to avoid npe (#34238)
we do derive stats job eager to avoid un derive stats due to merge group and optimize group
consider:
  we have two groups burned by order: G1 and G2
  then we have job by order derive G2, optimize group expression in G2,
    derive G1, optimize group expression in G1
  if G1 merged into G2, then we maybe generated job optimize group G2 before derive G1
  in this case, we will do get stats from G1's child before derive G1's child stats
  then we will meet NPE in CostModel.
