When DPP enabled, AQE won't work to replace smj with BHJ, so in Q95, there is one smj whose both sides are smj.

To fix this issue,

  1. we add a new strategy to split two wscg when smj are connected by build side.
  2. we also added a support to treat any operator as buildSide operator in smj.
  3. fix a bug when buildSide input is empty.
  4. Add a strategy that If only one side child is smj, then this side will be treated as streamedSide

Fixed: #22
