DRILL-5665: planner.force_2phase_aggr only overrides small inputs
The planner option planner.force_2phase_aggr was created for testing, but
may be used someday by a customer to allow spilling (currently single phase can
not spill).
That option was implemented unconditionally, thus potentially violating
other checks.
The code change is to only use this option to bypass a single check -- for
small input tables.
