[ESQL] date nanos binary comparisons (#111908)

resolves #109992 Nothing fancy here. Nanosecond dates are still longs, and we can just compare them as longs. Please note that, as mentioned in the linked issue, this only supports comparing date nanos to other date nanos, and not comparing to millisecond dates. With the cast functions added in #111850, users can explicitly cast to millisecond dates (or longs) to compare nanos to other things.
