[SPARK-12404] [SQL] Ensure objects passed to StaticInvoke is Serializable

[sarutak]

Now StaticInvoke receives Any as a object and StaticInvoke can be serialized but sometimes the object passed is not serializable.

For example, following code raises Exception because RowEncoder#extractorsFor invoked indirectly makes StaticInvoke.

case class TimestampContainer(timestamp: java.sql.Timestamp)
val rdd = sc.parallelize(1 to 2).map(_ => TimestampContainer(System.currentTimeMillis))
val df = rdd.toDF
val ds = df.as[TimestampContainer]
val rdd2 = ds.rdd                                 <----------------- invokes extractorsFor indirectory

I'll add test cases.

@sarutak thank you for sending this PR.

@marmbrus @rxin could you review it? I think this is a little big issue. We should fix it before releasing Spark 1.6.

[marmbrus]

Regression test please, for any patch that includes a bug fix.

[marmbrus]

So we can avoid delay cutting RC4, I've opened #10360 with tests added.
