[MINOR] [ML] change MultilayerPerceptronClassifierModel to MultilayerPerceptronClassificationModel

To follow the naming rule of ML, change `MultilayerPerceptronClassifierModel` to `MultilayerPerceptronClassificationModel` like `DecisionTreeClassificationModel`, `GBTClassificationModel` and so on.

Author: Yanbo Liang <ybliang8@gmail.com>

Closes #8164 from yanboliang/mlp-name.
