[SPARK-14653] [ML] Remove json4s from mllib-local
## What changes were proposed in this pull request?
This PR moves Vector.toJson/fromJson to ml.linalg.VectorEncoder under
mllib/ to keep mllib-local's dependency minimal. The json encoding is used by
Params. So we still need this feature in SPARK-14615, where we will switch to
ml.linalg in spark.ml APIs.
## How was this patch tested?
Copied existing unit tests over.
