The idea is to be able to express tests like this -- I will add a few more to show what is going on

here is some interesting behavior -- the filters get pushed down but the originals are left

This PR targets a PR in DataFusion
It adds basic tests for the filter pushdown physical optimizer introduced in that PR
It is largely based on the structure in influxdb_iox's query engine
https://github.com/influxdata/influxdb3_core/blob/26a30bf8d6e2b6b3f1dd905c4ec27e3db6e20d5f/iox_query/src/physical_optimizer/predicate_pushdown.rs#L24
I believe @crepereum and @NGA-TRAN were largely responsible for this code originally. To be clear, I am trying to give credit where it is due :) Any faults of this port are my own, not thiers
