[SPARK-15351][SQL] RowEncoder should support array as the external type for ArrayType
## What changes were proposed in this pull request?
This PR improves `RowEncoder` and `MapObjects`, to support array as the external type for `ArrayType`. The idea is straightforward, we use `Object` as the external input type for `ArrayType`, and determine its type at runtime in `MapObjects`.
## How was this patch tested?
new test in `RowEncoderSuite`
