This PR adds a check for invalid plans in AQE replanning process. The check will throw exceptions when it detects an invalid plan, causing AQE to void the current replanning result and keep using the latest valid plan. AQE logical optimization rules can lead to invalid physical plans and cause runtime exceptions as certain physical plan nodes are not compatible with others. E.g., `BroadcastExchangeExec` can only work as a direct child of broadcast join nodes, but it could appear under other incompatible physical plan nodes because of empty relation propagation. No. Added UT. Closes #36953 from maryannxue/validate-aqe. Authored-by: Maryann Xue <maryann.xue@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com> (cherry picked from commit 58b91b1) Signed-off-by: Wenchen Fan <wenchen@databricks.com> (cherry picked from commit 3cf3048) Signed-off-by: Dongjoon Hyun <dongjoon@apache.org>
