Support constant folding for insert values

[Caideyipi]

Summary

• defer table-model INSERT VALUES materialization until analysis so values can reuse IrExpressionInterpreter constant folding
• throw a readable SemanticException when an insert expression still is not constant after folding
• add relational session coverage for folded INSERT VALUES expressions

Verification

• mvn -pl iotdb-core/datanode spotless:check
• mvn -pl integration-test spotless:check -P with-integration-tests
• mvn -pl iotdb-core/datanode -DskipTests compile (fails in pre-existing generated aggregation sources: missing ComparatorChain / getModeMapSizeThreshold)
