Patrick Pisciuneri c7c6b642dc [SPARK-29121][ML][MLLIB] Support for dot product operation on Vector(s) ... ### What changes were proposed in this pull request? Support for dot product with: - `ml.linalg.Vector` - `ml.linalg.Vectors` - `mllib.linalg.Vector` - `mllib.linalg.Vectors` ### Why are the changes needed? Dot product is useful for feature engineering and scoring. BLAS routines are already there, just a wrapper is needed. ### Does this PR introduce any user-facing change? No user facing changes, just some new functionality. ### How was this patch tested? Tests were written and added to the appropriate `VectorSuites` classes. They can be quickly run with: ``` sbt "mllib-local/testOnly org.apache.spark.ml.linalg.VectorsSuite" sbt "mllib/testOnly org.apache.spark.mllib.linalg.VectorsSuite" ``` Closes #25818 from phpisciuneri/SPARK-29121.
