1. Add GlutenTest for failed get_json_object UTs:
   • Original Spark UT checks WholeStageCodegenExec, which doesn’t apply in Gluten.
   • Added GlutenTest Only validate via GlutenPlan and remove dependency on WholeStageCodegenExec.
2. Add GlutenTest for schema merging failure in GlutenParquetSchemaSuite,
   • Velox writes Parquet columns as nullable = true regardless of schema.
   • Before [#44644]([SPARK-46629] Fix for STRUCT type DDL not picking up nullability and comment spark#44644,, StructField.sql didn’t show NOT NULL, so Spark 3.5 tests pass.
   • Added GlutenTest Only test the nullable = true scenario to match Velox’s write behavior.
