typeintersect: allocation tuning for large UnionAll #54745

  1. typeintersect: reduce unneeded allocations from merge_env 

    `merge_env` and `final_merge_env` could be skipped
for emptiness test or if we know there's only 1 valid Union state.

  2. typeintersect: trunc env before nested intersect_all if valid. 

    This only covers the simplest cases. We might want a full dependence analysis and keep env length minimum in the future.
