… subquery ### What changes were proposed in this pull request? apache#41046 make `ReuseAdaptiveSubquery` become not idempotent. This pr reverts the change in `ReuseAdaptiveSubquery`. To solve the same instance issue when planning and reusing subquery in AQE, this pr makes `subqueryMap` hold the executed plan in subquery. Then in `PlanAdaptiveSubqueries`, each logical subquery plan can build their own instance of physical subquery. ### Why are the changes needed? To improve reuse subquery in AQE. ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? Pass CI Closesapache#41454 from ulysses-you/SPARK-43376-2.
