Subject: [PATCH] [fix](fe) Fix `FrontendHbResponse` serialization
 compatibility problem (#30337)

* Between branch-1.2-lts and branch-2.1, `FrontendHbResponse` has upgrade
  compatiblity problem, because `arrowFlightSqlPort` field, only metaVerserion
  less than FeMetaVersion.VERSION_121 will call `FrontendHbResponse.readField`

* Introduced by https://github.com/apache/doris/pull/24314
