   Hi team, just pinging this PR. It fixes a critical O(N) ACL scanning issue 
in StandardAuthorizerData.checkSection that causes ~3.5M iterations per 
MetadataRequest on clusters with many ACLs and topics. 
   
   cc: @cmccabe @ijuma (or anyone available to review KRaft authorization 
changes). Let me know if you need any adjustments!"
