[SPARK-12060][Core]Avoid memory copy in JavaSerializerInstance.serialize
`JavaSerializerInstance.serialize` uses `ByteArrayOutputStream.toByteArray`
to get the serialized data. `ByteArrayOutputStream.toByteArray` needs to copy
the content in the internal array to a new array. However, since the array will
be converted to `ByteBuffer` at once, we can avoid the memory copy.
