Description

Description

This is a follow-up of #15104. The benchmark was accidentally calling legacy code that writes the output of a varint group into a long[]. This wouldn't have happened if this code - which is only used by backward codecs - was in lucene/backward-codecs.

Contributor guide

Research direction
Identify the varint group code currently in the main codebase that is only used by backward codecs, and move it to lucene/backward codecs. Follow the pattern from #15104.
