[SPARK-3751] [mllib] DecisionTree: example update + print options
DecisionTreeRunner functionality additions:
* Allow user to pass in a test dataset
* Do not print full model if the model is too large.
As part of this, modify DecisionTreeModel and RandomForestModel to allow
printing less info. Proposed updates:
* toString: prints model summary
* toDebugString: prints full model (named after RDD.toDebugString)
CC: @mengxr @chouqin @manishamde @codedeft Small update (whomever can
