[SPARK-17629][ML] methods to return synonyms directly
## What changes were proposed in this pull request?
provide methods to return synonyms directly, without wrapping them in a dataframe
In performance sensitive applications (such as user facing apis) the roundtrip to and from dataframes is costly and unnecessary
The methods are named ``findSynonymsArray`` to make the return type clear, which also implies a local datastructure
## How was this patch tested?
updated word2vec tests

Closes #16811 from Krimit/w2vFindSynonymsLocal.
