Add session properties for small batch size mitigation
Summary: Add the relevant session properties that can help control and mitigate specific regressions.
Notably preferred_output_batch_bytes, preferred_output_batch_rows and max_output_batch_rows are existing velox query configs that were just not exposed.
row_size_tracking_enabled is to expose the newly added fallback to missing/failed average row size estimates.
