 Description   

This work involves plugging in the execution code added in SERVER-41962, SERVER-41963, and SERVER-41964 to the projection execution tree.

Specifically, we will add a new type of "child" node to
ParsedAggregationProjectionNode.

There will be three implementations of this new type of child node (one for each special post-processing codepath listed above). The post processing will be applied after the projections and expressions (see here).
