RoundingInfo serializes roughEstimateDurationMillis and unitAbbreviation but equals()/hashCode() omitted them, so instances differing only in those fields compared equal. Include both and add a regression test. This also fixes RoundingInfo[] deep equality used in InternalAutoDateHistogram.

AutoDateHistogramAggregationBuilder.RoundingInfoserializes five fields inwriteTo(rounding,roughEstimateDurationMillis,innerIntervals,unitAbbreviation,dateTimeUnit) but itsequals()/hashCode()only consider three of them, omittingroughEstimateDurationMillis(along) andunitAbbreviation(aString). TwoRoundingInfoinstances that differ only in one of those serialized fields therefore compare equal and share a hash code.This includes both fields in
equals()andhashCode()and adds a regression test.RoundingInfoequality also feeds intoInternalAutoDateHistogram.BucketInfo, which comparesRoundingInfo[]via deep equality, so this also makes reduce/result equality correct.Closes #151155
