### What changes were proposed in this pull request? There are several pr to fix compilation warnings related to `procedure syntax` like SPARK-29291, SPARK-33352 and SPARK-35526, in order to prevent the recurrence of similar problems, this pr add a compile arg to convert `procedure syntax` related compilation warnings to compilation errors in Scala 2.13. ### Why are the changes needed? Prevent the recurrence of compilation warnings related to `procedure syntax is deprecated` ### Does this PR introduce _any_ user-facing change? `procedure syntax` is no longer allowed in Spark code with Scala 2.13, for constructors methods definition should be `this(...) = { }` not `this(...) { }`, for without `return type` methods definition should be `def methodName(...): Unit = {}` not `def methodName(...) {}`. ### How was this patch tested? - Pass the GitHub Action Scala 2.13 job -- This is an automated message from the Apache Git Service.
