Fix stringFirst/stringLast rollup during ingestion (#10332) ...

* Add IndexMergerRollupTest

This changelist adds a test to merge indexes with StringFirst/StringLast aggregator.

* Fix StringFirstAggregateCombiner/StringLastAggregateCombiner

The segment-level type for stringFirst/stringLast is SerializablePairLongString,
not String. This changelist fixes it.

* Fix EarliestLatestAnySqlAggregator to handle COMPLEX type

This changelist allows EarliestLatestAnySqlAggregator to accept COMPLEX
type as an operand. For its return type, we set it to VARCHAR, since
COMPLEX column is only generated by stringFirst/stringLast during ingestion
rollup.

* Return value with smaller timestamp in StringFirstAggregatorFactory.combine function

* Add integration tests for stringFirst/stringLast during ingestion

* Use one EarliestLatestReturnTypeInference instance
