> Avoid redundant computation in GMM.transform && GLR.transform

> In SPARK-27944, the computation for output columns with empty name is skipped.
> Now, I find that we can furthermore optimize
> 1, GMM.transform by directly obtaining the prediction(double) from its
> probabilty prediction(vector), like what ProbabilisticClassificationModel and
> ClassificationModel do.
> 2, GLR.transform by obtaining the prediction(double) from its link
> prediction(double)
