Unnecessary ByteArrayDataInput allocations during aggregation query

Description

While doing some experiments with big5 workload on Opensearch, I noticed significant ByteArrayDataInput allocations during aggregation query execution. I noticed the allocations were coming from Lucene90DocValuesProducer$TermsDict.decompressBlock. I used below query for this experiment:

POST big5/_search?request_cache=false
{ "size": 0,"aggs": {"agent": {"cardinality": {"field": "event.id"}}}}

This is the snapshot from allocation flamegraph:

These allocations disappeared after running the experiment again with the changes proposed in the PR.
