### What changes were proposed in this pull request? Similar to SPARK-33441, this pr add `unused-import` check to Maven compilation process. After this pr `unused-import` will trigger Maven compilation error. For Scala 2.13 profile, this pr also left TODO(SPARK-33499) similar to SPARK-33441 because `scala.language.higherKinds` no longer needs to be imported explicitly since Scala 2.13.1 ### Why are the changes needed? Let Maven build also check for unused imports as compilation error. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? - Pass the Jenkins or GitHub Action - Local manual test：add an unused import intentionally to trigger maven compilation error. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
