Remove usage of SortedSetDocValues#NO_MORE_ORDS #88004
Description
Description
Lucene's SortedSetDocValues got a new SortedSetDocValues#docValueCount API that allows getting the number of values of a document without iterating through all values. We should change the iteration logic to use this count and consume count ords instead of iterating all ords until NO_MORE_ORDS is returned.
This should speed up some queries, e.g. value_count aggregations through the refactoring of FieldData#toString(SortedSetDocValues) to not iterate through all values to figure out the number of values.
