[FLINK-34675][table] Migrate AggregateReduceGroupingRule to java
What is the purpose of the change
A bit reasoning for the change
The reason is that since 1.28.0 ( CALCITE-4787 - Move core to use Immutables instead of ImmutableBeans ) Calcite started to use Immutables (https://immutables.github.io/) and since 1.29.0 removed ImmutableBeans ( CALCITE-4839 - Remove remnants of ImmutableBeans post 1.28 release ). All rule configuration related api which is not Immutables based is marked as deprecated. Since Immutables implies code generation while java compilation it is seems impossible to use for rules in Scala code.
The PR migrates AggregateReduceGroupingRule to java
it doesn't touch AggregateReduceGroupingRuleTest to be sure that java version continues passing it
