fix optimizer problem, we cannot do statistics propagation for those since it might lead to different state types depending on where aggregate is run

minor cleanup, orrification next

vectorized finalize and orrification for finalize and combine

add local state for combine and finalize to stop leaking

ensuring we have bound either finalize or combine

disallow custom window for export state

setting correct type on combine and finalize

re-enable optimizer for test
