### What changes were proposed in this pull request? Make Regressors extend abstract class Regressor: ```AFTSurvivalRegression extends Estimator => extends Regressor``` ```DecisionTreeRegressor extends Predictor => extends Regressor``` ```FMRegressor extends Predictor => extends Regressor``` ```GBTRegressor extends Predictor => extends Regressor``` ```RandomForestRegressor extends Predictor => extends Regressor``` We will not make ```IsotonicRegression``` extend ```Regressor``` because it is tricky to handle both DoubleType and VectorType. ### Why are the changes needed? Make class hierarchy consistent for all Regressors ### Does this PR introduce any user-facing change? No ### How was this patch tested? existing tests Closes #27168 from huaxingao/spark-30377.
