[SPARK-23042][ML] Use OneHotEncoderModel to encode labels in
MultilayerPerceptronClassifier
## What changes were proposed in this pull request?
In MultilayerPerceptronClassifier, we use RDD operation to encode labels
for now. I think we should use ML's OneHotEncoderEstimator/Model to do the
encoding.
## How was this patch tested?
Existing tests.
