Xusen Yin d6dc12ef01 [SPARK-13449] Naive Bayes wrapper in SparkR
## What changes were proposed in this pull request?

This PR continues the work in #11486 from yinxusen with some code refactoring. In R package e1071, `naiveBayes` supports both categorical (Bernoulli) and continuous features (Gaussian), while in MLlib we support Bernoulli and multinomial. This PR implements the common subset: Bernoulli.

I moved the implementation out from SparkRWrappers to NaiveBayesWrapper to make it easier to read. Argument names, default values, and summary now match e1071's naiveBayes.

I removed the preprocess part that omit NA values because we don't know which columns to process.

## How was this patch tested?

Test against output from R package e1071's naiveBayes.
