### What changes were proposed in this pull request? https://github.com/apache/spark/pull/39268 / [SPARK-41752](https://issues.apache.org/jira/browse/SPARK-41752) added a new non-optional `rootExecutionId: Long` field to the SparkListenerSQLExecutionStart case class. When JsonProtocol deserializes this event it uses the "ignore missing properties" Jackson deserialization option, causing the rootExecutionField to be initialized with a default value of 0. The value 0 is a legitimate execution ID, so in the deserialized event we have no ability to distinguish between the absence of a value and a case where all queries have the first query as the root. Thanks @JoshRosen for reporting and investigating this issue. ### Why are the changes needed? Bug fix ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
