      We are using optimizer::ConstEval to constant fold ABTs, generated by sbe_stage_builder_expression.

      Collation is not support in optimizer yet, so we need to create our own ConstEval ABT rewrite that supports collation.

      After discussion with QO team we decided to  copy current optimizer::ConstEval to stage_builder, simplify it to support only expressions and add collation support.
